I do hope Pinterest would fund memcached development going forward, especially the language clients for memcached. I've been using pylibmc to access memcached fast, and that project seems to be almost dead (https://github.com/lericson/pylibmc/issues).
client ecosystem is definitely a sore point now. I've just sort of started working on a replacement for libmemcached to hopefully cut down on the complexity... but then that's a migration and nobody wants to do that.
Pinterest should drop me a line if they're interested in sponsoring work though :)
