Personally, I'd like to see the board chart a course similar to option
4. Our ISPs need this address space NOW, not 3 years from now when
their multilevel NAT deployments are done. However, ARIN does not
provide the proper forum nor is the NRPM the proper mechanism to work
through and document the technical details which are not, as
previously mentioned, the same as RFC 1918. That forum will be found
within the IETF.

Hi Owen,

Let's call that the nuclear option. If the IETF won't be reasonable
and the ARIN BoT won't stand up and say, "hey, we're doin' it," we
could drag the shared transition space out of the established TCP/IP
standards process altogether. I'm not sure it's wise to create
precedent that gives other entities like the ITU a back door to come
after us for their clever ideas.
