Another solution a friend suggested: using "Parallels" thereby avoiding having to reboot to switch. Does anybody have any experience here?
I don't think Parallels is applicable for your purpose; it allows you to run OS X side-by-side with Linux or Windows, but I don't think it allows you to run two different versions of OS X.
