uPNP library

Need Windows uPNP API that uses the MS uPNP COM API ## Deliverables The API should provide me with the following details: 1. List of all available uPNP devices. 2. I can query each device and get its current uPNP routings. 3. Ability to add my own routing to a device and get the external IP of that routing entry. 4. Ability to remove any routing rule from a device. The API should not be multithreaded, I understand that the calls may block for a few seconds, also the API shouldn't use MFC and should work on VS6 and above.
