If you're Skype, there's no such thing as being too ubiquitous.
On Wednesday, the VoIP calling company will start making its new SkypeKit software developer kit (SDK) available for download. SkypeKit will give programmers tools (APIs, specifically) for placing Skype modules like voice and video calling, and instant messaging, into any desktop app or compatible Internet-connected electronic device running Linux.
SkypeKit will start off as an invitation-only beta, but developers can nonetheless request an invite. The SDK comes to device-makers on Wednesday and to Windows and Mac developers "in the next few weeks."
