I couldn't agree more, and it's for this reason that I increasingly 
think imposition might be best done natively as part of the PDF output 
process. By separating physical pages from logical document pages and 
using a logical->physical mapping for PDF output it wouldn't be too hard 
I think. Users could then be presented with a series of pre-set mapping 
styles and the ability to enter their own. The mapping would include 
page order, rotation, scaling and positioning.

Since the mappings themselves would just be an abstract data structure 
they could be saved to an XML representation for re-use, and for use in 
non-GUI PDF output.

Imposing pages from 3rd party PDFs would be accomplished through 
pdf-in-pdf embedding support (not yet available, but EVERYBODY wants to 
do it when it's practical), by placing them on a page. Because of that 
the imposition support would not need to worry about PDF input directly.

I suspect doing things this way would be the most maintainable, easiest 
for the user to get right, and generally most useful. Thoughts?

\What things would you expect the mapping to need to do/contain?
