Ahh, interesting, do you have any links to more technical information on 
how it works?  The website stays fairly high level.  I like the idea of 
multiple sources / multiple recipients, but I'm curious if the 
complexity pays for itself in the real world.  For example:

- Can a node simultaneously receive and broadcast the same stream, or 
need I receive the whole thing before I broadcast?

- Are the streams "live" in the sense that they have no predefined 
length, or is it merely "streaming" pre-recorded (fixed-length) video?

- How does a node splice feeds from multiple sources together in 
realtime to produce a single unified feed for playback?

Basically, is anyone doing anything like this, is it possible, and is it 
worth the effort?
