Classic ASP/VBScript Amazon Associates XML Interface

I need a "bare-bones" system to do the following: inputs: an amazon category, such as "billiards" (or an id equivalent) - should then perform the following: -traverse the ENTIRE category (including subcategories) and output ([login to view URL]) all of the available product info INCLUDING the directory/category structure. -the key feature here is the ability to enter a top-level amazon cat, such as billiards, and get all products within it, including those in any sub-category. This is a simple, single-function request, and no web interface is required. It must be written in classic ASP/VBscript, and it must be written in such a way that is "easy" on server resources.
