Skype yesterday announced SkypeKit SDK, a new set of software tools and APIs (application programming interfaces) that developers can use to port Skype to web-connected devices aside from mobile phones and computers.
SkypeKit is designed to work with a wide variety of chip sets, operating systems, and audio/video devices. Think of SkypeKit as a "headless" version of Skype--that is, it runs invisibly with no user display. That way, developers are free to surface and deliver Skype functionality through their own products' interfaces.
SkypeKit is currently in beta release. Starting June 23, develepoers will be able to sign up for the waiting list to receive an invitation to the SkypeKit Beta Program.
