That's a pretty sweet idea. I wonder how difficult it is to set up sharing of calendars, and the permissions that are involved in it.

Google Calendar lets you share only the Free/Busy times of your schedule, without revealing the details of each event.

Ideally, of course, your scheduler should be able to "propose" some times to George's, and let it decide and reply back with the chosen one.
