Running tasks remotely, via VNC?

Michiel,

Thanks for your reply. Unfortunately, our physical layout makes running 
more cables unlikely. Luckily, we usually have a 30 second-ish window to 
trigger our stimulus (one stage's worth of sleep), so a reasonable amount 
of latency isn't a problem.

Regards,

-Ted Snyder
