Exactly, about the shutout. Remember the project that siphoned juice from the audio jack to power sensors? That would probably be a no-go. I'm thinking about jailbreaking my iPod just to experiment with that project. The dock connector is actually pretty good for providing power and basic connectivity-up-to-a-USB-port, but I'm betting it would be shut down by App Store rules. Which is a shame, because Cocoa is probably one of the best frameworks for a researcher or hobbyist to build in. Which is where Google would come in: they could provide a great API for building out sensor platforms, not only in WiFi and Bluetooth, but also whatever 2.4ghz home-rolled or XBee modules people are using.
