Jeff,
Respectfully, do you see anyone from the big ISPs posting to NANOG
complaining about the impact of the routing table size in their
DFZ ? The big ISPs (e.g. many of them at the top of the 'Aggregation
Summary' of the CIDR report) can probably afford the routing table to
be twice the size (perhaps, if they're really big, their igp is
already carrying twice as many routes ... ?)
It's the multihomed enterprises, hosting companies, and smaller
regional isps who today take advantage of having the full routing
table to use, but soon might not be able to afford to, when companies
like the OP don't renumber into their new ISP's space when they
decide to change provider.
There's some debate in RIPE land right now that discusses, "what
actually is the automatic, free, right to PI" ? Every other network
in the world pays the cost when someone single homes but wants their /
24 prefix on everyone else's router. If one had to pay a registry
for PI, then small networks would have to think about the negative
externalities of their decision to deploy using PI.
Best wishes,
Andy
