A privacy-preserving system for sharing calendars would really be nice. Unfortunately I don't think these sites would work--I couldn't use them even if I weren't concerned about privacy because I'd have to hand them the keys to my corporate email/calendar account. This is definitely an interesting problem. :) Dudle is interesting, but possibly expensive in terms of cost to set up. The way things like that succeed in the IETF is that someone just sets them up and offers them, and then we find out if they are worthwhile. If they are, then maybe we spend the money making them official.
