cool, thanks for the link. I don't understand why they think BT is proprietary, though. It's being developed as a Sourceforge.net project,
http://sourceforge.net/projects/bittorrent/
and it's labeled "Public Domain".

It's also interesting to hear about the similar "Swarmcast" protocol they're considering. I'd never heard of it before but now Í see that there are several Swarmcast projects on Sourceforge, too.

Any idea what time-frame for any/either of these to be implemented?
