Re: Virtual Meetings

I wonder if in place of messages between users, the messages could be ones generated on the system and then "pushed" or multicasted to a group of users.  Maybe something like qsysopr messages, incoming sales figures, etc.    Very interesting indeed.

And I must agree that multicasting might be a better term to describe this architecture than "broadcasting", because each message  is simultaneously routed to a specific group of users, as opposed to everyone.

The screen is obviously cluttered at that point. I don't recommend that everyone try that because each "listener" uses a persistent connection to my HTTP server, which currently is configured for only 80 threads. Of course, I could dial that up to thousands of threads, and restart the server.
