This FFI binding uses CFFI/C2FFI to automatically generate the CFFI definitions, so it's a (mostly) complete interface.
zlib's gzip format can be used for compressing HTTP responses to browsers.

The primary communication channel is the facilities on the project's GitHub page.
The raw FFI part is almost complete (except some va_list stuff). It works well enough to be used in a web server to compress responses.
It doesn't (yet?) have any lispy extras over the raw zlib interface, but it seems to be fine without it.
It has an autoamted test that compresses and decompresses random data in random zlib configurations, and it doesn't yield any errors for me when run for minutes (besides some zlib peculiarities that are not excercised by default).
