Seems like it shouldn't be too hard for VMWare to run on Intel-based Macs. They already have Windows and Linux versions, so it's safe to assume that they know how to port their stuff.

Ask Bjoern Hansen has written them to enquire and reading between the lines of their reply seems to indicate that yes, they're going to do it.

Hmm...a fast Windows safely tucked in a sandbox on MacOSX would sure be attractive for many Mac users. I'll stay tuned.

And by the way, there's no reason why QEMU should not come to Intel-based MacOSX as well, they're running most everywhere already.
