The usual scenario is that the edge always has the most bandwidth. Its your
areas north of
the edge that can be bandwidth challenged.

It doesn't appear to offer any advantage when the peers and edge server are all
at the edge.
The edge server feeds one and only one client, and that client then branches
via virtual layers
to peer groups, all using unicast. IP multicast is more effective in this
situation.

I've seen one such box that does exactly this, but its problem was that it
exposed the notion
of 'downloading' and 'queues' to the user. Other than that, yes and no. Content
providers
prefer walled gardens, and so do CA companies. Also, RSS isn't designed for
carrying 'real'
broadcast data (how do you carry keys in an RSS feed) or handling billing (how
do you figure
out how/where/when to bill someone if the feeds are from diverse sources, and
how do you
securely automate this process). Its a nice first try though, but the modern
equivalent of a
wooden coach wheel.

Freenet is an anonimity service - so you can pirate movies without fear of
being traced. What
does that have to do with DRM? :-)

I believe if these technologies that are out there in their infancy now
continue to be
promoted for illegal downloading (the Engadget article is priceless -
screenshots of Battlestar
galactica divx'd episodes, clearly illegal), then the motion picture industry
will continue to
push away from them, no matter what advantages they hold.
