Great news!
Some quick ideas (not necessarily good or even desired) just "off the top"...
1. Multiple instances of the public repeater(s), just in case of problems. Possibly within separate VMs?
2. If necessary, different versions of the repeater, particularly during any public beta testing period.
3. Possible move of VNC discussions forum. (Better not to create two different forums at this time.) Though I think it makes sense to leave it as a subforum here. So I guess this isn't one I'd "like to see".
4. Publicly editable wiki.
5. Coordination software for hub collaboration with other developers (chat, irc, teleconference, whiteboard, etc.)
6. Possible test beds for similar projects, such as the French Java server/viewer whose name I forget.
7. A certificate authority. This is a biggie (and relatively easy). You can hand out certs in an effort to further secure things.
8. Other flavors to incorporate alternate DSM plugins or methodologies, including public key. As noted, I think the MSRC4 approach has serious drawbacks.
9. Secure relay (such as the fork you already host files for).
10. Dynamic DNS registry. I've mentioned this idea before -- people could not only track theirrepeater.chunkvnc.com, but optionally make that repeater publicly available.
11. Centralized mechanism for tracking friendly names versus repeater ID strings. Essentially, begin to duplicate GoToMyPC/LogMeIn "my hosts" functionality. I see this, also, as being incorporated into standard DNS queries.
12. Video tutorials.
That's enough for now...
