Oh, do you mean you fiddle the mtimes of the source files to be the same 
as those of the destination files, and you want rsync to therefore
not transfer them?  

Rather than going to all that trouble, why not just have your script 
produce an exclude file?

Perhaps you could also put a link to your script into the faq somewhere.
I'm sure other people would be interested in making gpg-encrypted 
backups.
