You should be able to use one of the Arduino drivers to connect it to
ROS. Another option might be the ZigBit modules from Atmel.

Also, it might be interesting to see a ros network driver for
ZigBee/802.15.4/6LoWPAN/etc to take advantage of the broadcast nature of
the network for sending data on topics.
