Routing advertisement ratios have always been capable of being in
peering agreements. Perhaps they exist in some. Who knows? Money doesn't
have to exchange hands to setup policies for your network.

Ummm. Let's see. Have you checked blacklists lately? While many are
pertaining to spam, the fact is that they are not "spam blacklists" but
"IP blacklists". Many of the largest networks have contaminated space,
and it's a crap shoot renumbering into them. There's also another issue.
Renumbering to new provider space means that you have to maintain
connectivity for both providers until the renumber is complete. With
large networks, this is cost prohibitive. Get a customer on your IPs and
they are loathe to ever leave you. Your proposal only makes ripping
off^W^Wkeeping the customer much easier.

Okay. Here's my issue and where I don't get it. I have my own space. I
interlink with multiple networks with and without export. I have to
handle the routes of all the networks, received from all peers. So do I
send out 120,000 invoices each month, or when I multi-home to I mandate
that my providers have to pay me for all of these advertisements that
*I* need to make routing decisions while I'm only contributing a measly
1-8 aggregates? Or is it because I'm the small guy, that I don't count.
I can be billed, but I don't get to receive money.

How are you going to handle the billing? Do you pay residually for the
networks or just pay a single fee? If you pay residually, do legacy
networks also get charged? If you pay a single fee, ATT, C&W, Qwest,
Microsoft, and a thousand other large networks will snatch up every last
one in bulk and then resell at whatever prices they wanted. Remember,
you can't manufacture more IPv4 addresses. In fact, we haven't even
instituted reclaiming processes for networks that can't show
utilization. We only slow down the consumption of what is left by
requiring such documentation.
So you look at the financials. You either make it so expensive that
companies can't stockpile the addresses, or Microsoft buys a /4 here and
a /1 there while AT&T is buying a /4 here and a /1 there. If you set it
too high, people who have valid need of the addresses may not be able to
afford them.
