I had this exact idea a couple years ago when the first emulators came out.
Using the real 64 would be much more compatible than the emulators,
and the PC should be able to handle even full GCR, etc. emulation fast enough
for the Commodore (much easier than handling sound, sprites, etc. on the
emulator such that it takes >=P590 to run at 1x C64 speed for most things).
At that point, I made a PC parallel to C64 serial cable and set out to 
make it so.  I never got the timings to work correctly, so the only function
I could reliably handle was the reset line :-).  I suppose I shouldn't have
been a wimp and messed with Borland C and instead should have gone pure
assembly.  Anyway, I got tied up in classes and haven't done anything since.
My code was nothing to build off of.  However, I do have confidence that
such a scheme would work, and if someone else has already gotten a 
start on such a project, I would be interested in it and possibly working
on features for it.
