Right. The problem here is that the pages *may* be generated dynamically
(dynamic fragmentation), and the fragmentation itself is a function of
the runtime environment. For example, access via Opera, or a PDA, would
result in something vastly different from something accessed via Netscape
The point being that the list of URL's, and the various flavors of them,
is potentially gigantic. For even a single targetted media (IE5, for
example), there could be many million URL's.

I don't get this. Often, the index size is about the size of the original
document (the larger the document, the smaller the ratio). I don't
see the benefit of making it available. What does the search engine index?
What links does it put in it's database? Does it put a link to the
Also, even though the URL's are stable (as they are the result of
a function evaluation), my point is that computing the full set of
links is potentially a tremendously expensive thing to do.

My point is that the document, does not exist until asked for... hence
generating the document, the index, and the entire list of URL's may
not be feasible... even on a static document.
