iCloud calendar invitations + GMail + Google Calendar

This is incredibly slick!

When you get a meeting invitation from an iCloud user on your GMail account, you end up with this. What's awesome is how the pieces fit together: the gray top part is contributed by GMail, pulling in calendar data. The bottom part, in blue, is the actual contents of the email, sent from iCloud. So you end up with the invitation framed in the context of the rest of your day.
