Thanks for the links, though; the first one was interesting to read.

Here's another interesting link in case you didn't see it elsewhere in your
thread

MAC on linux
http://www.maconlinux.org/

"Mac-on-Linux is a linux/ppc program which makes it possible to run Mac OS
in parallel with Linux.

MOL is primarily intended to be used by those who run linux/ppc as their
main operating system but still want to be able to run that occasional Mac
OS application. Other possible applications include:

   ? development
   ? hardware simulation
   ? server applications
   ? compatibility testing"

Don't get in trouble trying this on a work computer without permission :)
