Ok, I put you down for calendar, and acs_events. If you find you need help with acs_events, let us know and we'll see if we can come up with a volunteer to help out.
Since it doesn't make sense to have acs_object_util in site-wide-search, I'm going to fold it into the core. It only consists of five utility functions for acs_object_types, so it's not a problem.
