This is an example of PDF not actually being portable. Since it was created for standardized pagination, which is actually antithetical to portability of display, that's not a knock on PDF. (It's a knock on people who insist that PDF is great format for reference, I guess.)
If PDFs don't work on iPhone -- which was gonna be my suggestion for your best best -- then it's pretty hopeless. Wait until a portable format optimized for display gains widespread acceptance.
How about a pdf-like format that ran off of XML? Stuff could be tagged, and when read by a 'pdf viewer' (for printing or book-like reading with a current pdf-like interface), these tags would be read as bookmarks. When read by a browser or smaller-scale PDA-type device, these tags would be read as hyperlinks. The XML tags would determine how images/layouts/styles displayed.
Obviously, the file would have to contain more than just the XML and text content; it would also have images (background images, charts [possibly also XML-based], and artwork/graphics) and fonts (subsetted?), making for one file that was essentially equivalent to a pdf but would also serve as an entire website in one file package. For full integration, servers and browsers would be able to read this format for display on the web, as well as PDAs. The file itself (or the parameters of the file type) would offer instructions to each different format on how to display the XML.
