In re-reading your post, another thought occurred to me. You might also
want to look into Oracle's Advanced Queueing (AQ). You can set up
database queues so that one session acts as the "publisher" to
"broadcast" a message to "subscriber" sessions. Works kinda like async
inter-process communication using semaphores.
You can find info in the Oracle Developers manual. You can also find
some examples of its use at http://asktom.oracle.com.
