FreakLabs has an interesting project designed to conduct sniffing of protocols that ride on top of 802.15.4 such as Zigbee and 6LoWPAN (IPv6 over 802.15.4). The project utilizes their FreakDuino platform which contains an Arduino integrated with a wireless radio. The tutorial assumes that Wireshark is installed on your computer, the Chibi or chibiArduino release supporting promiscuous mode has been downloaded to the board, and that you’re using hardware that supports the protocol stacks.
While not a project for the beginner, this certainly looks interesting for the advanced Arduino hacker.
