My use case questions that still need to be satisfied are:
1) can any site (large or small) get a ULA-C?
2) can the ULA-C's be obtained at a nominal cost?
3) can the ULA-C's be published in the global DNS
forward and reverse?
4) can the ULA-C's be kept out of the DFZ?
If Paul's proposal answers all of these as "yes", then
I have no objections.
