Is there any documentation on TFS Web Services?

I am looking for any information on the Microsoft TFS Web Services. First I know accessing the Microsoft TFS Web Services directly is not supported and Microsoft provides no documentation for doing this. Therefore I am not expecting any Microsoft support or assistance here.

I know all about the .Net API available for TFS which only works on Microsoft Operating Systems. I have used these many times on Windows, however I need to do non-Windows work to access TFS, I cannot use .Net and I cannot use a Proxy (or "shim") to be installed on a Windows computer to provide Web Services for the .Net API.

I know Teamprise reversed engineered the web services and they successfully used this knowledge to make a very good cross platform Team Explorer and command line implementation in Java to access TFS. So good in fact they were purchased by Microsoft and the product rebranded and rereleased as Microsoft Visual Studio Team Explorer Everywhere.

I have also tested the .Net API against Mono on several non-windows platforms and they are not compatible. The initial NTLMv2 authentication is using calls not supported by Mono. They appear to be, understandably, making Win32 specific calls for NTLMv2 support.

Therefore before I go to the trouble of reverse engineering them for myself, and dealing with NTLMv2 to do it. I am hoping that there is some hidden or buried information on the web that someone may have documented some portion of the web services for TFS from 2005, 2008 and/or 2010.

Please no comments or posts about how this is not recommended or supported by Microsoft, that I should find a way to use the .Net API, or suggesting the Proxy/Shim is the best solution. I am fully aware of the Microsoft's official stance on this, and what the supported workarounds would be.
