Is there a Wireshark digimesh dissector?

Hello. I have designed an alarm distribution system on Digimesh over the last year, using an Arduino controller sending messages using API mode and the XBee arduino library.
Ive been experimenting with the TI CC2520 802.15.4 USB module to capture my mesh traffic with the aim of doing lower level analysis of my mesh performance that I can extract from the XBee UART.

The 802.15.4 dissector has a crack at interpreting the packets, but the interpretation is wrong, because it’s the wrong protocol. Address field bytes are wrong order, for example.

So, has anybody had a crack at creating a Digimesh dissector?
