Two carloads of geeks on their way to a perl conference connected their vehicles with WiFi access-points, then uplinked the whole network to the Internet via a cellphone. Why? Because "making a phone call from Pittsburgh to New York while both parties are coasting down I-70 in Illinois wasn't my idea of a smart move. I'd be more inclined to run into them to get their attention; it would have cost the same."
Meng and dha connected using talk on Schwern's laptop and we spent a good 100 miles just finding things to talk about. That's what happens when you work hard to build something that's minimally useful.
After rambling on about movies, making fun of each other's driving and deciding where to stop for dinner we decided to connect our network to the Internet. After all, we needed to send out proof that this was working. Once my cell phone reached a state of moderately reliable service, Meng brought up the link. We logged on to IRC and bragged about our connectivity. We sent email stating our coordinates. We acted like little children on sugar highs.
