postprocessing at distributed proofreaders is difficult
only because the proofers are instructed to throw out
meaningful data, which later then needs to be replaced,
and the formatters insert obtrusive pseudo-markup,
much of which later needs to be reworked or deleted.
if the proofers used nonobtrusive zen markup instead,
it wouldn't interfere with their proofing task, and there
wouldn't need to be a separate formatting task, even if
(in reality) people decided to specialize on that aspect.
also, the conversion of proofed/formatted pages into a
full-on electronic-book should be an automatic process.
i've already demonstrated this many times, but would be
happy to do it once again, on any book of your choice...
this point is particularly important in a roundless system,
where the object is to move a page to a "finished" status
as quickly as possible.
