Yes, I just tested right now to see how it behaves. As you can give several
memcache servers (for exemple your sql server and localhost), the session
went back a little time later thanks to CAS sso, but there has been a log

I have been told about repcached that replicates data beetween memcached.

By the way Michael, I've opened a ticket
http://bugs.horde.org/ticket/8116concerning memcache and msglistcache
