For the local LIRs I believe they already pay for this - they pay someone for IP transit. So this model seems to work for smaller LIRs - exactly the group of which many have stated they do not have the funding to continiously upgrade their equipment - especially not at the expense of someone else wanting PI space. Apart from picking one transit party over another unless I'm mistaken LIRs already default out to a bigger party these days already. The big boys - the parties that sell IP transit and hence connect in multiple regions - they would not to carry several more routes. I wonder if carrying /12s per region there would be sufficient - probably not. But on the other hand these are usually the parties that already have the bigger routers anyways. > and yeah, the idea is sound and I agree but can't really see an easy way > to implement it today... It is probably far from ideal - just came to me as a means to fix or at least bypass a hurdle for at least the LIRs that can otherwise not keep up with a growing routing table.
