The immediate goal is to speak pdfs, but you are quite right about other uses.  
Brad is trying to develop a general module for converting pdfs to xml.  The 
module could be used as a plugin for KPDF, but perhaps also in a general 
screen reader.  The idea is to develop a series of loadable modules for 
extracting accessibility information from document contents.  The module 
would probably be loaded based on mime type and perhaps would interface with 
AT-SPI.  Do you know if there has been any work on a standard for such a 
thing?
