You forgot the majority of PDF viewers:
* acroread
* ghostscript
* kpdf
* envince or whatever

Reinhard has my full agreement. Externally compressed PDF files
will cause lots of trouble and annoyment for the users.

If disk space is such an important issue, PDF-1.5 with
compressed object streams shows the way. The PDF viewers
will have to support this sooner or later.

For example, the hyperref documentation contains such links to other
PDF files.

And the main problem are users like me who don't want to unpack
the files first to read them.

You are screwed.

I would rather give up externally compressed PDF files and
switch to PDF 1.5 with compressed object streams instead.
