couldn't this be addressed to some reasonable agree by requiring someone to register their client and providing a fee schedule for "misbehavior" eg. if you send more than X requests per day per user you need to pay us $y per 100,000 requests over the limit (or whatever). the only requirement would be registering and providing billing info, which wouldn't be used if they behaved.
