actually yes. Gopal (gopalv@php) made a non-public (but working) prototype 
of a JIT PHP version. It was based on libjit (used by dotgnu).
I also have a good background in compilers and I would be interested in such 
project (as well as a better GC).

Forget APC. You can hook directly in the engine and do the JITing from 
there. APC could later be extended to also cache the compiled code, but at 
first shot you don't need it.

I don't think it is a difficult task to add JIT compilation to PHP, but we 
need someone that steps forward and do the first part and then convince the 
other developers that it is good.
Ah please remember that PHP works in a huge number of platforms (from a 
toaster to a mainframe), so the library you choose must be really portable 
and support many archs.
