so.. what businesses need is not actually 'more than one /48' but
real, useful, doable multihoming. A /48 is fine if you have only one
site, it's been used to solve 2 of 3 problems:

1) my addresses don't have to change (if I only have one site)
2) I can multihome with a single address on my devices/hosts (cause
the original v6 plan for that was just dumb)

It doesn't solve the problem of an enterprise with more than one
location/network-interconnect... we can go around this rose bush again
and again and again, but honestly, deployment of v6 happens for real
when there is a significant business reason to deploy it, and when the
real concerns of enterprises today are actually addressed.
