Various PHP libraries via https://github.com/ahiguti/HandlerSocket-Plugin-for-MySQL

Anyway this seems like a major win. All the bits are in place for this to be used. Nice thing about HandlerSocket is it gets around some of the limitations of memcache; if it doesn't work then just use normal SQL commands.
Thoughts/Ideas?
