No network admin? No problem if you have an iPhone and FaceTime!
FaceTime isn't the first video calling implementation on a smartphone but it's the first one that's easy to use and has a common and widespread install base, and that brings with it some interesting and decidedly futuristic advantages. Take this, which happened to a friend of mine today:
Our primary network administrator was off-site today and our backup admin was unexpectedly sick. So of course one of our business-critical machines decided to go down. I don't work in IT but I have a technical background and know my way around Windows so I was drafted to go in and try to "fix it". Needless to say one look at the Linux error screen and I knew I was in way over my head. Remote login wasn't working either. Luckily I have an iPhone 4 and so does our network admin so we jumped on a FaceTime call. I flipped the camera around, showed him the error screen, and for the next 10 to 15 minutes he talked me past them, got me to reboot the machine, restart the proper services, and relaunch the web apps our impatient users were clamoring for. It was a win all around. Never mind Santa. Apple should make that a commercial.
Apple ads have shown a lot of emotional, familial, even romantic connections over FaceTime but they haven't (yet) highlighted potential business uses. Information technologies is interesting. Medical and educational even more so. If FaceTime ever gets going over 3G (sans Jailbreak) and If Apple lives up to their statement that FaceTime will be released as an open standard, and other devices implement it as well, video calling could really become ubiquitous and it could be a great tool for any type of remote knowledge transfer.
