It's Philip, actually. =)

Very portable, but I should have mentioned that it requires you to  
distribute a C file that's compiled on the user's machine. That's easy  
to do via distutils but it adds a requirement to your app.

I don't know the answer to those questions, but it's just a regular C  
file, albeit one that's autogenerated. It comes with all of the pros  
and cons of a C file you'd written yourself.

Good luck
