I think that the best answer to the problem above is to provide more 
expressive markup language.  If html mathematics markup tags express only 
visual cues (e.g., superscript), then multimodal presentation will be a 
difficult.  However, if there are more meaningful tags (e.g., power or 
suptype), multimodal presentation will be better, and authors can be 
easily taught to use them instead.  

In physics, for example, the major journals all accept marked-up papers 
for publication, and after the initial adjustment most people are very 
happy with that.  The additional markup work eliminates a lot of tedious 
proof-reading, because the printer now knows the intention of the author 
much more accurately and thus makes many fewer mistakes.  Thus, serious 
authors are likely to make good use of richer markup if it is available 
to them (and I doubt that many people would want to spend much time 
reading mathematics, or any similarly rich text, from a non-serious author). 

I agree with your skepticism, and I think that the best way to solve the 
problem is by providing better multimodal document styles and more 
expressive markup.  I'm glad you liked the idea of multimodal style, and 
I hope you'll contribute to it.

Regards,

David
