Rate my startup, Go Test It (cross-browser testing)
seajosh: I did something similar a couple of years ago called Blue Violin. It was a web app that recorded web events, saved them, then ran the test script. The source code is available at http://code.google.com/p/blueviolin/ - you might find some code of use to you. If you have any questions, you can find me at @JoshWatts or josh.watts at gmail.com.
