I love the idea of an app startup logging program. If you can make hashes of each exe and track last startup, last changes to exe, etc. that would be even cooler. A long-term look at all this info, then make it exportable as a CSV and we can run some analysis on it, get some nice pie charts going and hey presto, unintended (but awesome) result is a graph of system update activity, system app load history, etc. Fun stuff. I like!
