Seriously?!  Please please please!

I'm currently in discussions about arranging a Masters degree (to start 
next Sep), using lilypond (and chuck and/or pd and/or Max) to create 
interactive music for a string quartet.  The lilypond portion of this 
involves compiling many short fragments of music.  (ie display 4 bars, 
computer listens to performers and creates another 4 bars, displays 
them, etc)

I think I can avoid the latency issues by creating the music one system 
in advance... but still, saving 1 second for each run would be great!  
Especially if I wanted to try having one computer displaying parts for 
two (or even four) people.
