NO! Just no. It is not so hard to allocate 24 million addresses amongst 
the plausible number of interested people in Victoria that we must 
consider doing evil things like further proliferating NATs.

One thing that could happen (not totally my idea admittedly) is that we 
run all wireless routing nodes with a single address from the 
172.16.0.0/12, with nodes then being able to advertise (allocated) 
blocks into this through an interior gateway routing protocol such as 
OSPF. The only reason any sort of organised allocation is needed is to 
offer the potential of summarisation, a technique of combining several 
contiguous address ranges into one larger range, to abstract some of the 
detail of the topology from other nodes. However in a situation where 
most nodes are expected to be multihomed, this doesn't work well without 
reasonable complexity and limitations on topology.

I personally think we should be able to expect sufficent performance 
from routing nodes that they will be able to live with running something 
like 500-1000 routes that change on the timescale of days to weeks. This 
would have been an issue when you had routers trying to do shortest path 
first algorithm on a large network with a 8086 equivalent processor and 
stuff all memory. However with a Pentium class box, it shouldn't be an 
issue.

I think the best way to manage allocations is through a structured 
system such as whois - as used by the professionals at APNIC, RIPE and ARIN.

Roger.
