Is there any chance the dupes are in different directories?  Then you have to recreate the directory 
structure so they don't collide (but I'm sure you thought of that).

So you could list out the files and unzip them one at a time.  If the file's already been seen 
rename it or put it in a different dir.

In Perl there are examples (in the bighorn sheep book if not the camel book) of using a hash to 
remove/detect duplicates in a list that happen to count the dupes.  That would make adding a number 
on the end easy.

HTH,
