Not all content works in RSS. While great for articles, news and logs, RSS can not represent what I call Hyper Documents.
A simple example is a web page that shows a geographic map. Clicking on an area of the map brings up the appropriate document. Assuming a map of the US this Hyper Document would consist of 50 state pages and 1 map page. This does not translate to RSS.
An option to explore is storing all 51 pages in 51 RSS items and then using OPML to loosely relate the items.
mmmm...
