w00t powah !

Yeah, we spent a lot of time on that with GrandVJ too.. we have an 8 
core mac here and it's pretty funny. each time you kick a new HD layer, 
a new core starts working like crazy (on that machine, we handle about 7 
1920x1080 layers at 25 fps btw).

I haven't looked yet how good live did spread across all cores.. I will 
do some experiment.
