[AG-TECH] Whiteboard in AG?

In the usual method of pre-announcing stuff that hasn't hit real code yet :-) I have some students working on multicast-enabling some of the realtime pen-tracking whiteboards (e-beam and mimio), which would/could include a mouse-driven whiteboard for the masochists. We're looking at wb/wbd/dlb and the various reliable-multicast libraries (and I've suggested building on these, rather than creating something new).

Several of our users have demanded this as 'critical', so we have to make it work for them.

Hopefully a delivery of code before the end of the year (or they don't pass :-) ). Feature requests welcomed, but may be left for later.

There's no reason I can see you couldn't use wb/wbd/dlb in the AG today, just that they're a bit clunky, old and unmaintained afaik. nte (network text editor) is another similar tool I'd love to see in the AG, which is somewhat wb-like, but focuses on shared text-editing. Anybody want to take that one on?
