Hmm.. that lets you run Windows under Unix, but does it let you run Unix
under Windows? I can't see any Windows version for download there.

If you just want an emulator that runs on Unix then there are a number of
other options. Xen is pretty cool; you can dynamically transfer a
*running* image from one machine to another, with downtime of just a few
hundred milliseconds. Main limitation is that you must run a customised
version of the hosted O/S to be able to talk to Xen's device drivers.

However, it would be quite possible to run a workshop with one Xen server
running a dozen FreeBSD hosts, and have people ssh and/or VNC into their own
virtual machine from Windows.

Cheers,

Brian.
