Just because I’m sitting here eagerly anticipating the arrival of my new camera (thanks for the recommendation John!), I was thinking that it would be cool to have a short-term notification service.  Something that sits in the taskbar (or whatever) and aggregates rss feeds for short periods of time.  To compliment this, for example, shipping companies would offer an rss feed for a tracking number.  The program would then aggregate that feed for the next 14 days or however long you specify.  When a change is detected, it would update the status and you could view the status at a click of the button. 

Yep, I’m just describing my utter laziness of not wanting to go to a website and enter the tracking number periodically.  I like the idea of entering it once and visually being notified by a program keeping tabs on when the status changes.  Sort of like those weather programs that sit in the taskbar.
