Kinda like #3s : I like the doodle approach (http://doodle.com/), and expand it to work out recurring meetings as needed.

Only problem is getting people to fill in all the data required to make it work.

Yes, the problem with Doodle is that it's incredibly inefficient to select a lot of different available slots of time. It also forces you to make a selection for specific dates. I need something that allows you to select your weekly availability (Mon-Sun) without asking for specific dates.
