Yes, but none of your three ways address the really fundamental issues of
how we build a VM.  All of them are fundamentally syntactic: they all ask
what the code we feed into the machine looks like.

We will have to answer that, of course.  But the question of VM semantics is
far more important.

Generally a bad idea; as you mention below, this adds lexing and parsing
overhead to the machine, and provides no real benefit.  Worse yet, it forces
the code to be transmitted in its human-readable form, which is a huge waste
of space.

Bytecode will work, but is a waste of space and time.  You can also
eliminate the lexing and parsing by using a compressed representation of an
abstract syntax tree.  Oberon-2 proved that it could be done;
http://caesar.ics.uci.edu/laski/portablecode.html is a project which is
attempting to produce more from that base (and has so far produced a theorem
prover and a Juice->Oberon converter written in C++).

What do you mean by this?

It really doesn't matter -- it's the same virtual machine either way.
