I often see questions like this in various forums:
We are about start the coding phase of our project. We would like to validate our architecture against someone with expertise in DCOM/Remoting/--Add your technology here--. We probably need a week or two of someone's time to provide a sanity check before we start our work. It is hard to find a resource, can you help?
You can open an advisory incident with Microsoft Developer Support to get help. Get the details at http://support.microsoft.com/default.aspx?pr=cntactms.
However if it is a quick question, please use the newsgroups.
