I've got an old PowerBook in the closet as well as an old firewire iSight. All they're doing is collecting dust. I've also got a baby, who also collects dust, but only by eating it. Anywho, I'm wondering if it's possible to somehow set up my PowerBook and iSight as a video baby monitor, and then broadcast that video locally as a bonjour website so that I could view it on my iPhone. Does software like this exist? Are there any free options?
