Can an iPod Touch have internet access if it's tethered to an iPhone running on 3G? 
That could be a cool app for someone to develop. It could potentially enable an iPod Touch to be used as a VoIP iPhone whenever there is no free WiFi available, since technically the iPhone would be being used as a router, and the iPod doesn't care where the WiFi signal is coming from, right?
