What do you mean by clever?
The "dumb" way is doing something like this (not tested)

   RewriteEngine On
   RewriteCond   %{REQUEST_URI}  !\.(html|php|other)$ # Allow  
requests for pages
   RewriteCond	%{HTTP_REFERER}	!^$                  # Allow if  
referrer is blank (you might want to change this)
   RewriteCond   %{HTTP_REFERER} !^allowedsite.com$   # Allow if  
referrer is known site
   RewriteRule   (.*) - [F]                           # Deny other  
requests

It's not perfect but I think this will do nearly what you want

   ThrottlePolicy Volume 5G 4W # Throttle based on volume of 5Gb over  
4 weeks.
