Telephony R.I.P.?

I have an iSight and a nice new Mac laptop. I also have a beat-up old Mac and a decent Canon videocam that I don’t use that much, not having (yet) developed videographer’s reflexes. Anyhow, the Canon has firewire output, so I plugged that into the old Mac and what do you know, it works just fine with iChat AV. So we put the old Mac and the Canon with a little tripod on a desk in a quiet but wired area upstairs and it’s a free videophone to anywhere in the world. Restating for emphasis: whenever I’m anywhere in the world and have an Internet connection, I can have a free videophone call home, that goes on as long as I need to and nobody’s counting minutes or running up a phone bill. Let’s see; free telephone with video, or pay-for-it telephone with no picture. Costly and voice-only, or free with a picture. I think this is what an inflexion point smells like.
