Hey Apple TV Hacks, I have started developing a Skype Plugin that will utilize the Skype API and make the user able to make calls and send text messages to anyone on there Skype contact list. As far as calls go, I think a standard usb headset or usb phone will work. Text messages will most likely be entered using the remote and the standard text entering method. No release yet, but I will release a beta as soon as it is able to make calls. Huzzah!
