I started modifying the Gateway plugin to include the skype4java API for access to a local runnig skype client, and so provide me remote access to a skype client via Jabber. I started integrating the skype4java API (osx only so far). Compiles, incomplete, but I dont really have the time to complete it, but thought someone here might.
There is also Karaka, which looks very promising… I’ve been trying to get it working, almost have it going… it is an external component that runs as a separate set of processes (not just a plugin) and manages starting/stopping multiple instances of the Skype client.
