[OS X TeX] off topic, breaking up pdf files.

greetings all,

this isn't exactly a tex question, but this list has so many clever 
people on it that it is tempting to ask here!

i have a tex-generated .pdf file that is hundreds of pages and 
therefore rather large. i have to share this file with a group of 
people, even as i update it frequently. since all the updates only 
append pages on.  since uploads/downloads through a modem (primitive, i 
know) are rather slow i got the brilliant idea i'd save a lot of time 
by splitting the file into a few chunks so my collaborators could 
simply download the latest chunk instead of the whole file.
to retain formula/heading numberings, i tried to do this in acrobat 
simply by opening the .pdf file, select "print", select a page range 
and specify a file instead of a printer.

to my surprise (i don't know much about fonts) the resulting file 
(containing only a fifth of the entire document) was substantially 
larger than the original! there are no graphics involved, but the 
original file is in landscape and the output is in portrait layout.

not surprisingly, the exact same thing happened if i repeated the steps 
in preview.

is this because the printer driver embeds the fonts in the output file 
for th printer to use, whereas latex simply assumes acrobat/preview 
knows where to find everything it needs?

is there a better way to split large pdf-files to make them more 
portable? (without messing with the tex-code?)

any help appreciated, thanks in advance.
