The only way these people see achieving this is if they can announce their prefix (of whatever size or status) to each of their providers and have it form part of everybody's tables.
Why should it form part of EVERYBODY's tables?
If we had geotop addressing then people could announce their prefix (of whatever size or status) to each of their providers and it would only form part of the tables in the same geotopological aggregate, i.e. the same city. The rest of the world will not see it at all.
The huge problem with this is the costs model, who to charge for what. Next to that the person you quotes wants "full control" which is something he won't get when you do geo addressing, at least not with the proposals made so far. PS: Could you please keep attribution, looking into the archives or other mails to find out who you are quoting above is really annoying. <SNIP>
We cannot assume that announcing a route will result in it being added to the global routing table. It is highly likely that ISPs will filter announcements on one basis or another in order to keep their copy of the global routing table small enough for their network to handle.
There is a simple answer here: pay enough cash to people and they will route anything you like. At a certain point only "payed prefixes" will be accepted and the rest can be filtered. Maybe a model where one can get a /48 from the RIR's when they pay them say $1000 dollar/month, the RIR then marks this prefix as 'payed' in the registry so that ISP's can filter on it will become viable at a certain point. Not paying your fee will make you filtered. *dream of global fully automated setups*. But this might already come with hopefully the (BGP) certificates that APNIC (*) is introducing. When your payment period expires and one didn't renew you don't have a valid certificate and thus your announcements are not accepted anymore... IP's will then really start costing money, but hey if your business is doing good, and you need the addresses then you get revenue for them anyway, simple business 101.
