About .net remoting authentication

Question

Hi.

I am want to know something about the two .dll files

Microsoft.Samples.Runtime.Remoting.Security.dll

Microsoft.Samples.Security.SSPI.dll

Which can be download from the following website:

http://msdn.microsoft.com/en-us/library/ms973911.aspx

http://msdn.microsoft.com/en-us/library/ms973909.aspx

 

Do Microsoft have roadmap to support it officially on the next versions of .NET?

Any special limitation of using these two dll files?

Any legal terms associated with it?

 
And last question, how to contract Microsoft by email or mail. It seem like I need to provide an AccessID and a Microsoft employee's name, but I have neither.

Thanks
