There's always the Mono platform too. But I'm not certain on Microsoft's future plans for Skype.
You can bet after paying 8.5bn for Skype, Microsoft aren't going to stop supporting it on other platforms, haha. The only real heavy Microsoft integration I can see is natively integrating it in to some of their flagship devices, such as Windows, Windows Mobile, XBox, etc. (and obviously providing a superior and more seamless experience than software on other devices, which are only really ever going to be apps). I think last I read, there were close to 300 million people using Skype, so no, it's fairly safe to assume they would never restrict it to Windows Microsoft devices.
