No, you don't. That wasn't what his question was.
Yes, I know there are drawbacks, but if implemented correctly, the
benefits far outweigh them.
No there aren't. At least not in the context of memcached. There are
plenty of other technologies out there that do exactly what you want,
MySQL being one of them. Memcached's core functionality is the speed
and performance benefit you get from not having to access a physical
disk to return data. Using it in this manner is counter intuitive to
it's purpose and afaik, there is no such way to extend memcached without
actually patching the source code yourself.
