It may be very easy to get it routed for free *now*.

Will it be possible to get PIv6 routed for free once there's 300K entries in
the IPv6 routing table?  Or zillions, as everybody and their pet llama start
using PI prefixes?  (Hey, if you managed to get PI to use instead of using an
ULA, and routing it is "free", may as well go for it, right?)
