I think it would have to be something a bit more generic. I suspect  
we'd want to add that feature previously discussed where an external  
script would approve all files before they're uploaded. But not to  
run the script for every file, because that would be horrendous, so  
you'd want to communicate over stdin/stdout.

IOStreamGetLine and LocalProcessStream might be good classes to use,  
and you could reduce the impact on the rest of the code by using a  
class derviced from ExcludeList.
