On a completely unrelated note, I started playing with EvoCam today as a way to piddle with my iSight. It seems pretty cool, you can force it to do some pretty neat stuff like only record when there is motion. It can also upload via sftp, which is very, very cool. I recommend checking it out if you’re looking to do more with you iSight
EvoCam can also send images as an email, save them to folders, even record video. It also has it’s own web server that supports authentication.
