Makes sense, how often is jitter in that regards a problem and if it is 
a decent amount of time, what might be done to help with that problem?

Yea a ms or less definitely wouldn't be a problem for what I am thinking 
of.  I tend to think slightly higher might not be a problem either, but 
I was worried it might get over, say 3 mS which I think might cause a 
problem.  This is overall between GUI and communication.

That is good to know and exactly answers my question I think, thanks.

Again thanks for the information.

Was definitely considering it.  I suppose my question there might be, 
while I don't have intentions for it currently, I don't want to rule out 
the possibility of the FE running on a separate machine, and I would be 
worried about packet loss with UDP over a network or possibly wireless 
connection (Not looking for wireless for show conditions, more for say 
in a theater show when I might be setting cue levels by running a FE on 
my PDA).  But yes OSC is definitely looking like a good possibility.  Of 
course I haven't looked to see if there is an OSC lib for my PDA much 
less most PDAs;)
