Does skype have an api from which it would be possible to create a browser plugin so that when a call comes into skype it will let the current web page know that there is a call (with the caller ID information)
回答1:
I think that you are looking for Skype Accessories (the Skype Public API).
Skype Accessories enhance the Skype experience for Skype users. They can be hardware products or software applications, but they're all created by developers who use the Skype Public API, a text-based protocol, to interact with Skype software.

There is no server-side solution for this that won't breach Skype's TOS (logging into the Skype network using user credentials).
