} ISPs don't want to use a /31 because it is also wasteful: to establish
} point-to-point links between the gateway and N customers, you need 2N
} addresses instead of N + 1 addresses.

     Then don't pretend it is point-to-point when it isn't (most
"broadband" technologies aren't truely point-to-point).  And, if
it is truely point-to-point then that's the way it is.  And, 2N is
a heck of a lot better then 4N.
