Who cares? Voice is only 56 or so kbps. Just give it absolute queueing 
priority, and suddenly you have negligible jitter...

People are doing various kinds of video over Internet 1; works fine.

Why should it?  There's a cheap, ubiquitous, widely deployed broadcasting 
medium already.  I never understood network integration for the sake of 
network integration.

In any case, TV (of all things) does not have problems with latency or
jitter below 10s of seconds.  All TV content is pre-packaged.
