Hopefully someone from force.com labs reads this or someone forwards it to them.  When I tried to install this into my production org there was an error in one of the test cases.  It said something about querying too many rows.  I imagine that a limit clause needs to be added to one of the queries in a test method.  If you are able to communicate with force.com labs or are reading this and work in the group please verify that this issue will be addressed.  Thanks.  Here is a link to the app iCalendar Export 1.1: https://sites.secure.force.com/appexchange/listingDetail?listingId=a0N300000016fTNEAY.
