Not really. None of these systems generate sample clocks from
network messages. Local clocks are free-running and not synced.
Signals are resampled to match the other end, and the quality
loss resulting from doing that is accepted, as are the effects 
of lossy compression. Such quality loss is not acceptable for a
standalone audio interface.

Yes. See my previous post. IMHO, soundcards should be free
running if only one is used, synced by word clock links 
otherwise, and any network-derived timing used only to
align the delays. That will be tricky enough.
