Howdy,

I want to only allow my users to have a single session at a time. The
act of logging in should invalidate a session that might have been
created from another devices as well as sending that device a notice
via the channel that the session had ended.

I actually had this working on my dev server. I used a singleton to
hold a copy of the session object and channel information, and when
the user logged in from a different device, I would invalidate and
send a message. The problem is that since GAE the production server is
distributed, I have no guarantee of the same JVM on each call.

Reading through docs and group post, the only possibility I could
think of was to retrieve the session object from the datastore or
memcache. Is it possible to read the session object from the either of
these locations? If so what is the key and object type?

Thanks a lot,
Scott
