Hi,

If you need replication/high availability for cached objects, I'd recommend
you to examine Tokyo Tyrant and Tokyo Cabinet, as a replacement of
Memcached. Tokyo Tyrant acts as a network interface for concurrent access to
Tokyo Cabinet databases -your persistence layer-, implementing memcached
protocol. Thus you don't need to alter your memcached clients.

And you have ruby bindings for that :-)

Hope it helps

Cheers
Alex
