Rendezvous - Persistent session URL for multiple uses over an extended period (i.e. rehearsal & show on separate days)
Be able to have a persistent session URL to send to participants so that you can rehearse within the system days before the actual live stream. Then have them re-join using the same link on a different day.
This would reduce confusion over which link is correct, and also would mean the participants were assigned to the correct sources in the Wirecast show file.
Its funny you mention this today Nick Djukanovic - I was on a call earlier today with someone who usually uses Wirecast and Skype in a studio, but wants to go mobile with a laptop occasionally. Without the full out-board mixer and standard rig, he was going to look at Rendezvous.
After explaining the workflow problems with Rendezvous - he gave up very quickly, and got a portable mixer and replicated a smaller version of his live studio for mobile broadcasts.
This one is a no-brainer, and has been requested years ago. No new code, just a configuration element that will increase the session age as a workaround until the whole join/invite system is overhauled.... but thats another story for another day.
