I think you'll have plenty of work to be before you get to the stage
of needing a box with more than 4 cores. Even a dual core machine is
likely to be enough for initial experimentation, I would say.

The other thing to consider is that there are several other VMs out
there, including many under open source licenses, that can be used as
a testbed. Examples include the Java VM, Mono, Parrot, LLVM, etc.

Not me! I'm not an academic... I've never had a paper published and
I'm not likely to either.
