Calendar and Booking Plugin

Update: Check out our new Events & Bookings Plugin, which does pretty much what you guys were after

There are 2 plugins that I would really love to see you guys make, and they are kinda related.

A Booking plugin where visitors can schedule appointments or make reservations. WooThemes ventured into this a bit with their WooTables, but it leaves a lot to be desired.

and

A Schedule plugin where you can add new events through a custom post type, and add a date to it from which a calendar is generated showing the different events.

Would anyone else find these plugins useful?
