Developing a site includes several steps, from design, implementation, testing, marketing etc.
Part of the marketing could be Google AdWords… and speaking of Google. Providing a dynamic Google compatible sitemap feature would be nice.
The next post describes a solution:

However, according to the post, this feature should be part of the ASP.NET futures project… which currently is part of the ASP.NET 3.5 SP1 Beta 1.
And the ASP.NET 3.5 SP1 Beta 1, I assumes it is part of ASP.NET SP1 
I have however not been able to find this feature, either by using Google or Reflector… I will look into this later.
That I have done now… if you are still reading, take a look on these link:
