Apple Concierge-type Script?

[Aperture]

Does anyone know if there is an app/script you can install on a website similar to the Apple Concierge software? I'd be interested in customizing it to fit a specific purpose and was wondering if anything like it existed.

Thanks

Edit: Just to clarify, I know there are several PHP calendars out there but there really isn't anything as pretty as the Concierge.

I'll be honest, I have no idea what that is. But after Googling I found a blog post pointing to "Scheduley", might that help?

Thanks for the link, I'll definitely look more into it. Ideally, though, I'd like to run it off my server.

By the way, The Concierge is a web app that helps you schedule Genius Bar appointments, training sessions, etc online.
