Thanks again.

Did you have the chance to take a look at the Apple document? I realized that the procedure outlined there does not work as expected, or at least it doesn't work with frequently changing calendars like that of OmniFocus reminders.

So, in the end I gave up on the idea of receiving reminders both on my iPhone and on the Mac (which I had somehow taken for granted would be the case), and subscribed the iPhone to the reminders calendar in the old fashioned way (i.e. MobileMe not pushing any updates to the device, but rather the device pulling any changes either manually or at preset intervals).

At least now I do not have a duplicate reminder calendar on the iPhone, as I did earlier. Changes are also synced from the iDisk to the iPhone calendar in a predictable and consistent manner.

If MobileMe treated calendar subscription as equal citizens to the regular calendars, I would have been perfectly happy. The current solution is not bad, but there is certainly room for improvement.
