As Shawn pointed out, this potential expensive operation would not happen 
too often, just like calculating hash sums. So on checking for new files, 
only new files (not in KPA's DB) would be checked.

However, I can see your objections. Maybe we could make it configurable? (I 
know, another configurable option which isn't really required)

I'd say this is another topic: the file exclusion problem, which is still 
not resolved :(

just my 2¢,
