He's the devil, I'm just his advocate. 

Good.  :-)

Sure; people who supply lots of bandwidth to content providers *now* will 
probably be unhappy about this idea, but...  no business is guaranteed 
its business model; that observation goes back at *least* to Robert Heinlein's
first short story, "Lifeline" from 1954(?)... and I *think* he was quoting
Supreme Court Justice Learned Hand, but haven't been able to source it.

The real problem I see myself is that *the Mbone has to be pervasive* (or
mostly so) for this to be a worthwhile investment for providers.

Not to mention it being practical for eyeballs to *get* to it; haven't seen
that HOWTO pointer yet from anyone.  :-)
