David -- the proposal did _not_ have a theory of how it would work. It
did not acknowledge scarcity of bandwidth as a problem.

Now Geza is starting to suggest mechanisms to limit the number of
users. That is a lot more reasonable. A bit of analysis of the actual
bw required per-stream, and how that would work in a wireless env
would show some very surprising things [*] that IMO change the model
completely.

But the bubble needed bursting. We don't have infinite memory, cpu, or
storage. And damn we have limited spectrum!

* - for example. How does the bw consumption of streaming look if you
are using infra mode (with a conventional AP) and the stream server is
on an XO? What would be the impact of running a reflector on a machine
that has a wired connection to the AP (ie: the XS)? What would the
impact be of running the stream from a wired connection to the AP
directly?

I think a bit more serious thinking up front that leads to success...
hey, I'm so old fashioned man. I like to succeed, and I like GSoC
students to succeed :-)
