We'll have some "PI" in the global table, of course. But please look at Alex Le Heux' numbers that will be presented on Thursday morning (about 10:00) on what makes up the bulk of the current IPv4 routing table - and you might be surprised.
Is this presentation available online somewhere for those who can't be in Amsterdam this week and for whom the time of the prezo is not so convenient to participate remotely? There doesn't appear to be any pointer to the presentation material on the RIPE 62 meeting plan. I'm curious to see whether the drivers for global routing state have changed since I gave similar presentations a few years ago. FWIW, I'd assert that the dual role of IP addresses as both endpoint identifiers and routing locators means that finding a scalable solution that allows both provider independence and scalable routing is basically impossible without implementing separation of those roles into two separate numbering spaces.
