Sam, the duplicate reminders issue is a MobileMe problem - it's not something we can fix in our code.

The current calendar publishing was implemented as a means to an end - folks wanted reminder alerts on their iPhone OS 3 devices. The calendar app was the only way to get those reminders onto their devices.

(Apple didn't make the code that Calendar uses to pop up notifications available to third party developers, and push notifications don't work for the 40% of the marketplace that has an iPod touch.)

Bill's post about repeating actions is why the notifications are only pushed out for a couple of weeks. Farther than that, the events you need to be notified about may not have been created yet...
