perhaps you'd be willing to pick up the pen on
<http://nsa.vix.com/~vixie/ula-global.txt> which i personally abandoned
in 2007 or so? william herrin had sent me a long list of things that
needed fixing. i'll be happy to send that list, and the nroff source
code, to anyone who wants to restart it.

i don't see why we'd base the long future of ipv6 on the short past of
ipv4, or why current RIR policy fails to meet the needs of ISP's. so to
me this problem seems unrelated to ULA.
