Let me offer this observation. If there is a more or less absolute need
for efficiency of this type, consider that all of the pertinent text
information is really contained in the Scribus .sla file. This file can
be transmitted with a lot less overhead, especially if you're just
talking about text. There are only two requirements on the receiving end
-- a working copy of Scribus compatible with the Scribus file type
(1.2.x vs 1.3.x), and the correct fonts (though subs can be done in a
To some extent I guess the reason for the "inefficiency" of PDF files is
