Skype API COM wrapper
The SKYPE COM API is a simple COM object that enables you to add SKYPE functionality to a variety of applications (Websites, Outlook contacts, ASP Pages, .Net applications).
QZoxy released Skype COM API wrapper, which allows non-C++ developers easily to hack around Skype API in Windows Scripting Host environment. It seems that as of this moment an API doc in PDF is only available.
