Mostly preexisting code/hardware for transport management and the
wisdom the RFC has to offer.  One should only be breaking well agreed
upon/tested/polished rules of thumb when one is very conscious of why
one is breaking those rules.

As it is, RTP is as perfect as anything we'd come up with ourselves.
No need to reinvent the wheel.

No, just the meat-and-gruntware powering IP delivery.

RTP is just the one-step-above wire-level protocol.  On top of RTP
there's still plenty to do.  For real application level compatability,
we'd be talking abotu the abstraction level of, roughly, RTSP.
