New software called Swarmplayer has been released which allows a live or video on demand stream to be shared over a bittorrent derivative. This software installs easily into windows and ubuntu. I put it on fedora but it's a pain. p2p-next consortium (who wrote swarmplayer) got a 19 million euro grant to develop this for the EU cable tv over internet system. This looks like it's going to become a standard.

For those not yet briefed on the nature of bittorrent:
Bittorrent is a file transfer program which allows the uploader to give a little piece of the file to each downloader, and each downloader trades pieces with every other downloader, allowing an unloader to upload a file to 1000 people as fast as uploading it to 1. Regular files download fastest when you are the only one downloading, bittorrent turns the tables and downloads go fastest when the most people are downloading. When bittorrent users are done downloading a file, they get to share pieces with others, educating the people with their spare internet. Finally, bittorrent defies firewalls. If the great firewall of china were set up here, bittorrent can be set to tunnel it's tracker communication (download list of peers) through tor or a proxy server. The firewall can't block all peers who have the files, and it can't block bittorrent without blocking all encrypted communication.


Download the program http://trial.p2p-next.org (note: the test streams appeared to be down)

Some video on demand content is here: http://eztv.it
explanation of how to download it here: http://eztv.it/tstream/tstreamhowto.html

more content here: http://www.cs.vu.nl/~arno/vod/

This code still needs tweaking so for now, it seems to work best with low bandwidth content. I think this should be tried out for carrying the 32k audio stream. As this is tested and p2p-next works the bugs out, the stream could probably be upgraded to a 200k live video stream. Eztv.it is using this software to distribute HDTV content, I don't know how it well works because I don't have fiber optic internet :)  With help from Alex's servers this should be easily achievable for prisonplanet members. This software could theoretically be installed in fancy camera cell phones making them into super web cams (live wearechangecam?)       
The video on demand feature acts like youtube. Since youtube is coming under increasing control, this seems like a viable alternative. Also the users who enjoy the video on demand offerings can leave the player running to share the movies with others, taking virtually all load off of central servers.

Then the server budget can be shifted to redundancy rather than bandwidth. The thepiratebay.org folks know how to make a site impossible to remove from the internet (they would also make an interesting interview)

To Alex and Co. If you decide to start using this software, I'd be glad to give instructions and guidance for installing it on Redhat Fedora. I can also give you scripts to run the broadcaster off of the infowars stream. Or I could make a FC9 i686 disk image with the broadcaster ready to go.

The term "Anti New World Order" is like the term "Anti Federalist". The old world order was worried about their power structure being replaced by a "New World Order" of the people, so they designed a system of world government to prevent it and called it the "New World Order". Like the Anti-Federalist Society, the anti-NWO movement is really the new order of the world.

  • Wake up call...the republic has been stolen.
   If this really works...this will be the invention of the wheel in streaming media terms.  I'll have to research this further to look at
corruption vulnerability, etc.  RIght now I belong to a consortium which distributes an audio program via torrent as a trunk line
of sorts, and then manually repost the mp3 files by hand at secondary distribution sites.  This may be something to look into
in the coming months.  Combined with the eventual 802.11s wireless mesh networking standard rollout this could be very interesting.  :)

This seems like an amazing idea, but I cannot understand why so expensive to produce. Various BitTorrent websites let you stream movies from them already, and so the only difference here is it comes from your camera to the torrent, instead of from a file.

And of course, you will need a decent amount of people to be seeding for this to work smoothly. The performance is going to be very variable.

This is CERN's "Grid".  Ultra high speed data sharing, but you do not own a hard drive or memory, it is all done ISP side, with approved programs, and approved content only

Sounds to me like Torrents are the modern day model for the Grid, which itself is set to be the world standard by 2012.

Welcome to the Internet 2.

Yeah, doesn't http://vuze.com do that already?

WATCH THIS FORUM, WHEN ALEX GOES LIVE, I MAY POST A LIVE TORRENT OF 16k OR 32k AUDIO FEED FOR BENCH-TESTING.

Vuze is peer assisted. Meaning there is a central server which is helped by the peers, and which has software you don't have so you have to clear the tv stream with them. Other examples include SOPCast, and PPLive (that one is impressive.) Swarmplayer is the first software that is pure peer2peer, no central server or broker.

Your description of the "GRID" sounds awful, but if nobody (is allowed to) own(s) a harddrive, there must be massive server farms storing the data. Kinda the opposite of bittorrent making data widely distributed over thousand of harddrives across the world, isn't it? I wrote a little article here: http://forum.prisonplanet.com/index.php?topic=65656.0 about the internet2 and some ways to prepare for it. Remember that more often than not, the technology intended to control instead liberates.

This will likely be unstable if left entirely to the peers, but Vuze and PPLive prove that with a central server working with the peers, amazing stability can be achieved. And if the computer which the stream is broadcast from is on a fat internet pipe, it will act like a central server.
