I think you'd want to do a /60 so it's on a "nibble" boundary.  But by 
then you might as well do a /56.

My personal feeling is that 99% of  home networks will use a single /64, 
but we'll be giving out /60s and /56s to placate the 1% who are going to 
jump up and down and shout at us about it because of some reason that 
they feel makes it all unfair or that we're "thinking like ipv4 not 
ipv6" etc.

It's possible that home networks will gain some ability (in a standard 
fashion) to use more than one /64, but I doubt it - it's much easier to 
do resource discovery on a single broadcast domain for things like 
printers, file sharing etc.
