Suppose there is a piece of machine code. There is a theoretical program 
which could examine this code at runtime and make appropiate changes to 
alter it's behaviour. These chances would be simple (changing all [ds:eax] 
to [cs:eax], or adding prolog/epilog).

Given that the actions of the machine code are not known in advance, the 
design of the code is arbitary (wierd flow, self-modifying etc are possible) 
and there can be no human intervention, what obstacles are there to a 
runtime analysis/modification program?

Theoretical problems and theoretical solutions, however impractical, are 
relevant.

I have a killer (simple) idea for copy protection but i need a little 
perspective first :)
