I'd throw it on a duino clone on RF like a Moteino and pass it to a gateway. I'd \
really like to integrate a serial device natively via a custom device in owfs on a \
gateway like a Pi, but haven't dug into that yet. 

Sounds like the arduino 1wire emulation on a wired interface would work fine as well. \


I think, however, that a custom device that would allow generic wireless creation of \
emulated devices would do wonders for moving owfs forward with the push for wireless \
sensor nodes.
