Io

http://github.com/iamaleksey/memcached-client-io/tree/master - libmemcached based

Protocol

To write a new client, check out the protocol docs. Be aware that the most important part of the client is the hashing across multiple servers, based on the key, or an optional caller-provided hashing value. Feel free to join the mailing list for help, inclusion in Subversion, and/or a link to your client from this site.

Also, see the forthcoming binary protocol docs.
