Yes, you can do this. The Rendezvous java classes need to be made available to
your server's JVM (much like you'd load a JDBC driver or other non-EJB
classes) - how to do this varies depending on what server you are running.
You may also need to modify the server's security policy, as Rendezous
needs to do socket i/o and load native libraries.

Correct, you can't do this directly, but you can have another Java process
accept TIB/Rendezvous subscriptions and have it call a SessionBean via RMI.
In some cases it may be possible to run this subscription code inside
the server's JVM (e.g. Weblogic and some other servers support installing
custom initialization code that runs at startup).
