[Building Sakai] Webservices in a cluster?

[Maurer, Christopher Wayne]

What are folks doing about webservices running against a cluster?

If I call login from SakaiLogin.jws, it gives me back a session (on a particular node).  If I then make some other call passing that session id, it may be serviced by a different node and be unable to find that session.

I have not done too much with webservices before so am not fully read up on them!  We are running 2.6-ish.
I've been looking around a bit here:

But haven't seen anything that has been terribly helpful.
