I'm trying to emulate the message exchange between Safari & Mobile Safari when remote debugging (using Node).

I've sniffed the traffic between the two; they're exchanging binary plists over TCP. I've managed to replicated the packets up to the point where a particular tab is chosen for debugging ("socket setup"), but after this Mobile Safari ignores my plist instructions and instead sends back a listing.

Here's the raw tcpdump of the socket setup packet Safari is sending, and a JSON representation of the plist it contains:
