They mailed recently and asked if we could give them our thoughts on
calendar server-side, and I said something like "ummm... our thoughts
aren't very well-developed" ;-) but yeah, interested in working with
them.
They're still in heavy devel but I think they'll be an interesting group
to interact with. They've gotten some fairly serious backing from the
common solutions group and their tie-in with I2 is something to think
about when thinking about desktop deployments and calendars.
Universities are interesting users of desktops - specifically of
calendars.
