IPv6 end user addressing

[bmengel at gmail.com (Brian Mengel)]

In reviewing IPv6 end user allocation policies, I can find little
agreement on what prefix length is appropriate for residential end
users.  /64 and /56 seem to be the favorite candidates, with /56 being
slightly preferred.

I am most curious as to why a /60 prefix is not considered when trying
to address this problem.  It provides 16 /64 subnetworks, which seems
like an adequate amount for an end user.

Does anyone have opinions on the BCP for end user addressing in IPv6?
