To quote U2, I still haven't found what I'm looking for. However, I just came across this app-to-be-released that looks closer than anything else I've found thus far...

http://www.rescuetime.com/

RescueTime is a web-based time management tool (currently in private alpha). We offer:

    * The ability to see exactly how you spend your time. No data entry, no effort-- Your time gets tracked down to the second without you having to actively track it.
    * Instant and easy time-management analytics. Instantly know how much time you’re spending on a particular application (like “Microsoft Word”) or a particular category (like “Communication”).
    * The ability to set time management goals (daily or weekly) and receive notification when you meet (or fail to meet) your goals.
    * Tools to see how you compare to other people in your industry.

Sounds promising...

Bruce has been tweaking this program for years to the delight of users everywhere. It would be cool if it was handed over to someone else, but if not, it remains the most powerful tool in my belt. Saves me a countless number of hours in all areas of computer use.
