While I realize Python extension modules are pretty much the norm in CPython, it'd be pretty cool if xz support could be written overtop of ctypes.  ctypes seems to be emerging as the way of doing FFI across different python implementations.

I've been working on a backup engine in my spare time, and I'd very much like to use a Python xz module in it.  However, the code I have so far runs about 4x faster on pypy than CPython, even if I turn on psyco in CPython.

IOW, I'd be pretty pleased to see an xz module that works equally well on CPython, pypy (seems to have pretty good ctypes), jython (has the beginnings of ctypes in 2.5.2rc*), iron python (supposedly included recently)...
