Javascript/Ajax Event Calendar :: BackpackIt.com Calendar Clone

We are looking for development of a javascript/ajax based calendar for a non-profit company. A good example of the simplified functionality we are looking for in a event-based calendar is at : http://www.backpackit.com/calendar

And an overview movie of the features:
http://www.backpackit.com/example_movies/overview.mov

And even all of the things that backpack calendar has would still be too many features (ie: don't need multiple calendars). We are looking to implement this calendar into a django based application later down the road. We will need it to work outside of a django-based application first using a mysql database is preferred. Because we will be implementing it in a python environment later, we do not wish to have it rely on PHP, ASP, etc.

Now that you have an idea of what it is we are needing, if you could get back to us with your ideas/thoughts/etc that would be great.
