It would be really cool if Skype allowed SkypeIn and SkypeOut to be bridged, so I could have my Skype client running, and set it to dial my mobile phone (or whatever number I happen to be near) over SkypeOut whenever it received a SkypeIn call.

Even cooler if I could leave Skype running on my home broadband connection and send it commands via the web to change the number it calls when it gets an inbound call, thus allowing me to call the nearest phone to my physical location.

That would be truly awesome.
