Talking about DVI and PDF, I am the first one to be concerned about  
the programmed extinction of DVI because I have many jobs based on DVI  
post-processing (for example for marginal material, headers, and even  
for parallel texts between two pages). The advantage with DVI is that  
you can very easily now where you are located on the page so that you  
can extract text with positional information, and you can also easily  
insert new text (using pushes and pops).

But I'm confident that I will be able to rewrite all that for the PDF  
format. Multivalent has released some very powerful Java classes which  
convert PDF into a human-readable format and back to binary. Of course  
BT...ET sections are more complex than DVI's SET operator but I think  
it is possible to do simple post-processing.

And with the Mars format there is always hope that all that will be  
written in XML...

So, although many of the tools I depend upon are based on DVI, I'm  
rather for a PDF-only solution.

Nevertheless, a problem that should be solved is the one of adapting  
psfrag to PDF. psfrag is *absolutely essential* when typesetting
