Initial Comment:
Adobe Reader has a'reflow' feature that allows 
visually impaired users to zoom into properly 
formatted documents and read them without having to 
move the viewable area back and forth across the 
page.  PDFs made in MikteX eith pdfte are not properly 
formatted and reflow without interword spacing, 
redering them unreadable. I contacted the MikteX 
people and they referred me here. I beleive Scientific 
Word also uses pdftex with the same result.

Any chance this could be fixed?

I'm changing the summary. Yes, we are aware that tagged pdf
is an often requested feature, but implementing it would be
- first pdfTeX would have to be extended with primites for a
structure tree (and classes and packages would have to use
these primitives)
- then primitives for tagging the content are needed and
must be used

I would volonteer to test the feature. I am writing
a rather long pdf produced with pdftex that is 
downloadable for free ( http://www.motionmountain.net )
and readers regularly ask why it cannot be read aloud.
Pdftex probably would only need to be extended
with a single command - something like 
\writetaghere{tagtype} - and all the rest could 
be done by extensions to the latex cls and sty files.
