Well, if this is going to be the small guys against the big ones I  
wouldn't want to be in the shoes of the small guys. But it hurts the  
big ones too, so I don't see any reason except inertia that at least a  
few of them wouldn't want to get on board with something like this,  
unless they like the idea of an upgrade cycle and think they can  
afford more expensive routers that their competitors.

There are many differences. With SPF records you can't easily see how  
many people use them. Also, SPF was something new, not the failure to  
do something that everyone thinks is reasonable in the first place.

And apparently it worked once AOL got on board.  :-)
