Yep.  There is a command line that you can bring up (and hide) from 
where you
can change to another face (using code or UI).  Also there are keyboard

The vast majority of recent notebooks (in the last 3 years) support all 
the basic rendering
in hardware for things the Audicle needs to do.

This is an intriguing idea - especially since we have a large research 
group here at
Princeton doing shared high performance computing with very low latency 
(Kai Li's
shared virtual memory, and the Princeton display wall - synchronized 24 
cpu).  This
could very well lend itself to this.  Also, we can use multiple hosts, 
and use network
to synchronize or to otherwise compensate for the different clocks on 
the sounds cards.
