See https://gerrit.wikimedia.org/r/#/c/187074/ and https://github.com/AaronSchulz/python-memcached-relay/blob/master/mcrelayd.py for the prototype daemon.
I'm not terribly wedded to any language/tool, but this only need to be able to keep up with write-level traffic (not memcached GET level volume), and I'd like to keep it simple.

python-memcached-relay -> might be worth renaming that, since it also covers redis and plans to do varnish/squid too. I'm happy to review it as soon as you have it up on gerrit.
