[virtmach] Implementing VMs efficiently

[Peter_Murray@allegiance.com.au]

I feel that methods of dynamic optization seem to be blurring the line
between the virtual machine and the compiler.

I've long wondered if it would be worthwile distributing a compressed and
possibly encrypted intermediate representation of a program along with, or
instead or, the byte-codes.  This should enable better optimisation since
the optimizer theoretically would have a better idea of the "intent" of the
application.
