I think it might make sense to revisit the ideas in the BBN protocol,
but start with the latency model of a modern wired and wireless LAN,
and define a simplified protocol for this special case.  Zeroconf is
an example of a protocol that limited itself to "networking in the  
small"
and was very successful, and I think speaker synchronization could
be just as successful ...
