I like IP.Calendar, and I'd like to see it mature in featureset a bit more. With that in mind, these are three features I would find useful:

- Restriction to only accept a certain number of RSVPs
- Restriction to only allow members in certain usergroups to attend
- Restrictions on who can see your event based on postcount, usergroup, time registered, reputation, etc

I was just going to post the same info. here. At least how many total can RSVP and their user group.

This would be an extremely useful feature.
