Remember that memcached is only a CACHE, it's not a data repository.
Records will expire and the cache manager is in control of expiry. You can not
trust it to be reliable.

Most of us just replicate the database or forward the REGISTER messages between
two SIP proxys. That's why you have an option to SAVE() to make it not reply,
only silently update usrloc.

That way you can run in kamailio memory. You will not survive restarts of the 
proxy though.
