My preferred solution is to use HTTPService, pass parameters in the POST, and call an aspx page. The aspx page does all the server work, using VB.NET (I am considering switching to c#). The aspx page gets the parameter values from the request, builds an xml string and response.writes it to the client. On the client, I use resultFormat="xml" and the XML class members to manipulate the data.
I don't have any "runnable" samples, but I can send you the code from one of my aspx files that does the above work if you think it will help.
