I have in my previous life (before I got out of the game). Think VPN logs (intensive mode recording) for several thousand users over a two year span....data mining for one user to defend against a multi-million $ class action suit. Unfortunately, I couldn't use mainframe "big iron", with sufficient processor/memory, but instead using SQL on servers....talk about the wrong tools for the job at hand (but it's all I had to work with at the time)
