I've recently written a basic dissector for the Apple USBMUX protocol (which
encapsulates TCP traffic), as used by devices running the iPhone OS, using a
combination of guesswork/reverse-engineering and consulting various documents
from around the Web.

It currently dissects the first few bytes of the packet header, and a hacky
attempt is made to dissect the actual TCP payload - although despite trying
various techniques for payload extraction, it doesn't quite work as I'd expect.

I'm submitting it in the hope that others find it somewhat useful, or have
better ideas as far as payload extraction is concerned.
