Ah, the joys of the overly-simplistic idea that it makes sense to
associate one program with a given extension.

If this is (easily) do-able under your favourite OS, could you write a
program which, when given a PDF, Does The Right Thing and calls either
AA 5 or AR 9 (or whatever) on the file, as appropriate?  And then
associate this program with '.pdf' ?

(I have a shell script which does a generalization of this: when
passed one or more file names, it checks my rules to see which program
I want to use for that/these file type(s), and runs the corresponding
program(s) on the file(s).  I have found it much easier to do this
than to fuss around trying to get the right entries into .mime.types
and other similar things.)
