Implementing such a system would change the way large(global) LIRs request space from RIRs. As of today, they would typically request one /32 per RIR. For people the size of Sprint, they would then have to request a /32 per country they service and assign space to customers from the correct prefix.
It is worth noting that the current IPv6 policy is not restricted to allocating /32s. LIRs moving large numbers of IPv4 customers to IPv6 can receive shorter prefixes: <http://www.ripe.net/ripe/docs/ipv6policy.html#ipv4_infrastructure> 4.4. Consideration of IPv4 infrastructure Where an existing IPv4 service provider requests IPv6 space for eventual transition of existing services to IPv6, the number of present IPv4 customers may be used to justify a larger request than would be justified if based solely on the IPv6 infrastructure. For this reason, it probably makes sense to take account of existing IPv4 usage when considering this issue. Regards, -- leo vegoda RIPE NCC Registration Services
