It certainly wouldn't, but that's not the issue.  Writing a 68K virtual
machine on the 800 would be comparable to writing an 80x86 VM.  Have you
ever used the SoftPC product?  It works just great, except it eats your 800.
Emulating a dissimilar architecture is a lot of work for the *computer*
as well as the programmer.  I can't fathom how you could expect a 5-10% 
performance difference!
