Last I did much research on it, the only semi-working implementation of OSX
in a VM required VMware Workstation as the host, involved booting a hacked
together boot cd image, and crashed and burned hard on updates. It was
interesting, but not very viable for anything that's of any measurable
importance at all. I tested it out for a couple days to compile a little
pice of code a mac user friend wanted to play with... it was dog slow on my
system otherwise (but that was likely my system's fault, old E8400 @4GB ram
at the time + Win7)
