Printer capabilities: if I get Owen correctly the gnome print dialog already
deal with it via CUPS, no need for mozilla to worry.

Driver capabilities: if we extend mozilla postscript driver to support all gnome
print capabilities what sort of problems you expect ?

Site policy: could you point me to docs or code where the possible policies are
defined ?

I dont think it's useful to make the gnome print support all possible
combinations of mozilla drivers but rather to use one of the mozilla drivers
(postscript with an intermediate file could be the easier solution) to be able
to print through gnome print.
