Don't forget: one size NEVER fits all.

/56 is a really bad size because people will be tempted to think it's  
enough and then run out AFTER they've deployed enough stuff to make  
renumbering hard. So...

In my opinion, we should give a /48 to everyone who wants one, no  
questions asked. Everyone else should get a /60. /60 is a good  
balance between wasting address space, standardizing on a fixed size  
that works well for 99% of all users and getting people to go to a  
larger block before they've painted themselves into a corner too much.
