Why not ? That is not because it was not meant to do it that it would be
a bad idea to do it.
I know there are issues with memcached (ie concurrency), but there also
are advantages (cost & performance being the main, I lack the first and
need a lot of the second).

Spread is fine, but last time I tried it, I did not manage to scale it
to the level I needed (> 1000 writes/s).
