At the moment I am just parsing wireshark dumps for my protocol decoder, so I would be very interested in this too!
I can get a bit of a wiggle on with my python  stuff so you can at the protocol level decode it (well assuming I did it right), for decoding I more or imitated the look of a raw representation of blockexplorer. I am about 2 weeks away before I can release anything decent but I should be able to put something halfway working on within a couple of days, if anybody is interested.
