[pdftex] pdftex & file size...

I face the following problem, which was always there, but gets quite
annoying in this peculiar case...

I have a PDF file (a small (150 p.) science book with 80+ images,
most of them vector arts, and hyperlinks).

i make the PDFs for images with distiller, they use the same fonts as
the main text, from (AI, fontless) EPS of 50 K, I get PDFs of 300 K
(imbedding or not the fonts makes essentially no difference, and
obviously pdftex does the good job of factorizing the fonts in both

the output of pdftex is 23 MB
if I distill this to a PDF at 1200 dpi, I get a 2.5 MB file.

The pdftex file being the one (after optimization) intended for web
delivery, this is almost inacceptable.

The pdf consultant of acrobat 5 can't reduce it by more than a few
K's, what is puzzling is that it thinks that 95 % of the objects are
of type 'unknown' (which appears to be 45 % after distillisation)

Does anyone here understand why pdftex files are so big?

Is there out there any solution (even a commercial plug-in) that would 
allow the kind of optimisation that distiller does, _without_ killing
the hyperthings?
