You could, but I'm not sure that's it's intended purpose.  As I understand it, the PersistentManager
is for pushing session data that hasn't been used in a while out of memory, thus allow a Tomcat
server to handle more sessions with less memory.

This is my understanding as well.  Sessions are persisted to the database periodically instead
of on-demand.  If you need sessions replicated as changes occur then you'll want to look at
a different solution, like the built-in cluster support.
