Oh, don't get me wrong - I'm not going to give anyone a hard time for
assigning /48 for households. I was asking only because I've spent
some time recently on various v6 address plans and by default I'm
assigning /56, so I'm just wondering if I'm missing anything and there
is any good reason for assigning /48 (the only reason I can think of
is 'one day that site might want to be multihomed...').
