a) Begs the question of whether any of our transition tools are robust
   enough to support serious real-time streaming use.

b) PPP/TCP looks like a reliable link with very erratic timing
   characteristics.  I'm fairly certain that unidirectional streaming
   protocols can deal with that via buffering (so that it's not real
   time anymore).  Whether the deployed implementations can or not is
   another matter.

   Bi-directional real time may be hard enough that (a) applies.
