You can have shared sessions across cluster nodes if you want now. You can either roll your own or use one of the various existing implementations. Two implementations come to mind as both were built by people in my CFUG. The first is rSession by Brian Ghidinelli, which stores the session struct in a database. The second is fsSession by me, which stores the session struct in a shared file system. They both work basically the same way, but use different storage techniques.
