This has been on the todo list and I took some time tonight to look at the Drupal Events API so I think it's also very doable. It would be great to both allow folks to maintain a calendar here and import/syndicate information from ical feeds (like Google Calendar provides) as well as "current location/status" reports from twitter and others...

It's always good to hear what features are most interesting/useful. I'll bump it up the list.

Thanks, Maj
