These are exactly my recent thoughts and which led me to get 
reacquainted with Forth as the basis for a "re-programmable" plug-in. 
It's hard then not to consider a Forth based VM bootstrapped from the 
image itself, although I'm not yet sure this is even a sane idea :-) I 
wouldn't be surprised if someone has already considered and rejected it.
