Yes and no -- it depends on how nice I want it to act.  How much time I 
spend on the infrastructure vs. the musicality and algorithms is 
something we'll be determining later.

I already have it working (on a single computer) in chuck and pd.  In 
both languages, I simply write lilypond code into a text file, call 
lilypond on that file, then call "open foo.pdf" (which in osx opens it 
up in Preview, of course).

My first example was called "sadism" -- it began by giving the cellist 
random notes from a D major traid, and listened to the intonation.  The 
worse the intonation was, the harder the notes got (ie more distance 
between notes, notes outside of the scale, etc).  It was surprisingly 
easy to make... but of course, that was just a simple example, for a 
single musician, on a single platform.

I could easily extend that to a quartet -- have one laptop for each 
member of the quartet, with a directory of a fifth laptop remotely 
mounted.  Whenever a new .ly file appears in there, the quartet member 
laptops copy it to themselves, run lilypond, etc.  Of course, this is 
quite inefficient; I'll definitely do something better than this.  But 
how much better is still an open question.  :)
