I kind of agree.  I think the first part (only the folks that  
seriously have a chance of getting to the podium at the NATS will buy  
full 2 meter bi-planes made of space aged materials) is not quite  
true.  There will always be the wannabees who have the $$$$ who will  
show up with them as well.  The problem is whether the "second tier"  
pilots will feel and respond to the pressure to have the airplanes  
the "big boys" have and that could drive the costs.  There's another  
factor that bothers me about a rule like this.  I once overheard a  
comment from a judge which went something like, "That pilot must not  
be a serious competitor because he doesn't have....".  I know he was  
a "bad" judge, but....
