Our calendaring plugin is the only closed source library we use and an unfortunate error with the license keys has caused it to expire on midnight of 24 May 2009. This problem is now resolved and an automated test implemented in our system to ensure this cannot happen again. At ish we tend to avoid closed source libraries whenever possible for exactly this reason: we were eventually able to diagnose the problem by decompiling the library and discovering exactly what it was doing, something that is far easier when dealing with open source code libraries. On the other hand, this calendaring plugin is very reliable and gives us the gorgeous interface you see in the calendaring parts of onCourse.
