Ray,

Yes, this would be an easy and accessible way to handle the captcha issue. 
however, it would also be a very easy way to write a bot to respond to the 
sent email with the ID.  This is the problem.  Writing automated systems 
to do this kind of response is pretty straight forward.  So the difficult 
thing to do is to have a system that you cannot be easily automated to 
respond to.
