"The above-mentioned RFC3177 goals can easily be met by giving home  
users a /56 assignment by default."

I disagree. A /56 is still wasteful if we assume that home users are  
only going to need a very small number of subnets.

Additionally, many people will be tempted to start using a /56 for  
purposes that really need more subnets than about 250. Renumbering  
when a network needs its 257th subnet will be painful. It would be  
much better to a have a clear distinction between very small networks  
and all other networks, and not have a size that is still to large for  
most while at the same time being too small for some, even if they  
don't realize it at first.

So I'd like to see /60 for consumers and /48 for anyone who feels /60  
isn't enough.
