I think we do need to consider alternate routing methods and network
technologies, but I think that they need to developed in the appropriate
forum (IETF)  and implemented by the appropriate folks (network
operators).  I think we need to make sure that ARIN policy supports the
existing network technologies, without inhibiting future innovation.  To
that end, I think that IPv6 PI space is necessary for the same folks that
need IPv4 PI space (so they can migrate from IPv4 to IPv6 with minimal
changes to their network), but that non-PI multihoming techniques
(advertising PA space into BGP, using shim6, or any other new multihoming
method) should be preferred for folks without a compelling need for
provider independent addresses.  IMO that compelling need is directly
related to the difficulty of renumbering when changing providers, which is
large for the types of organizations that currently get IPv4 PI space, and
small for most of the folks who don't.
