Have a project coming up which would be well served by a wireless link between the microcontroller (and its surrounding interface stuff) and a string of Dallas OneWire temperature sensors. The gap needs to be waterproof and electrically insulated but (apart from potting/cover etc) the two bits could be pretty much touching.
I know there are one or two nerds hanging around here - has anyone played with the RFID gear that might be found in a bike key/barrel for example? Have any joy, any gotchas?
