A few months ago I came across a package on GitHub called Ultramemcache, which was described as “Ultra fast memcache client written in highly optimized C++ with Python bindings.”
Using Ulramemcache, I modified the common python-memcached library to use Ultramemcache, making sure it could be used as a drop in replacement. Check out python-ultramemcached on my GitHub page.
I also put together a django cache backend using Ultramemcache. This currently does not require my python-ultramemcached library. Check out django-ultramemcached-cache on my GitHub page.
