Protocols like H.232 need special support in the NAT box to work at all,
and even then, they break if the customer has more than one box that
he wants to reach from the outside, like "a PC in the living room and
one in the office", which could be done with a /29.

While I do not advocate giving everybody a /29 (or a fixed address at all,
for that matter), I don't think that NAT can be the answer for every
customer network.  Some are quite happy with NAT, others want to do things
that are not supported by current NAT boxes, so we should not try to 
force NAT upon them.

If the IPv4 address space runs out, let's go to IPv6... it's there :-)
(but I agree it certainly needs more work).
