You said you were using memcached for sessions but memcached does not
support replication, so it's unusable for your purposes, even though
the SP supports the protocol for session storage.

So I suggested to use a replacement for the memcached server --
specifically Couchbase Server -- that *does* support replication and
uses the *same* *wire* *protocol* as memcached.

Seemed to me that would provide you with clustered sessions on the
server-side, using existing and Free/Libre/Open Source software (Shib
SP with memcache protocol support as client, couchbase server as
server) and somewhat established protocols (memcache).

The server also happens to have an API which may help achieve your
goal of terminating sessions administratively, I would think.

Is the suggestion sufficiently clear now?
