Having an iCal subscription that updates with changes of the program or starred events would be really nice. Currently, one has to redownload and replace previously downloaded calendars when something has changed in the program or the collection of starred events.

From John Wickerson:

When I download my personal conference program, I get a static .ics
file. This is a great feature, but it would be better if it could be
implemented as a subscription. Then, I could change my mind about which
events I want to attend, and then open Calendar on my mac and it would
have automatically updated. At the moment, downloading a new .ics file
each time, and removing the old events from my calendar, is a bit of a
pain.

For now: Only for personal schedule, not for other filtered programs
