Whip out an HTTP debugging proxy and I'd imagine you could get pretty close to unpacking Skype's API in less than a day. It uses the Bond protocol, which is easy enough to deserialize, and some tricks to verify that the message being sent is really the one that should come after the last one that was sent. I didn't get as much time as I would've liked to play with it so they may have more tricks waiting, but it looked simple enough from an hour or so of tinkering.
