Calendar plugin
 

I build mobile websites using WordPress (specific themes for mobile) and want to be able to put up a calendar on a page that a customer/client/patient can use to make an appointment with me.

An example to illustrate the concept would be tungle.me. There, it hooks into my google calendar. But rather than just "view" my calendar, a person could book an appointment with me.

Does anybody make a WP plugin that hooks into the google calendar that allows for this "interactivity?"

I cannot find anything...
