I was thinking about going over the SRD, turn it into HTML, and make it cross-linked all over the place (so that if, for example, there's a reference to the flaming sphere spell somewhere in the text, that would link to SRDSpellsF.html#flamingsphere (or something like that).
Then I realized that doing so would take a metric buttload of work, and that it would be foolish to do so since the SRD will be outdated in a few months anyway. I might do it for the 3.5 SRD though.
