I dont know if anybody has started working on this. However in a previous post it was mentioned that Patchou was already working on this. I guess he will be able to give an update.
Then just a small comment to the icon on the desktop. I think that it would be just fine if the status-icon was the same as in the "normal" MSN window. I dont think there is any reason to introduce a new icon. Of cause I will leave that up to the people making the feature
