I have an iFilter for zips, I also have one for HTML, and I have one for CHM - but the workstation versions, at least, don't appear to be 'configurable'.
Given that iFilters exist for PDF, CHM, XPS etc I'm sort of surprised someone hasn't written one for ePubs. I suspect the reason there isn't one is because the earlier versions of the various "Desktop Search" programs were all deficient and flaky, so the whole idea got a bad reputation.
However, the Desktop Search that comes with Windows 7 is significantly better, even though its built on the same underlying indexing service using the same iFilter based design and implementation.
I've contacted Citeknet (iFilter 'specialist') to ask if they are interested in doing one, or if not whether they could make the source for the CHM iFilter available to me so I can roll my own.
