APNIC, ARIN, and RIPE are now *the* members of the Address Supporting
Organization (ASO) of the ICANN. Just as, IETF is now a part of the Protocol
Supporting Organization (PSO).
This could turn into a globally over-arching problem. MAPs has a large user
base that is international in scope. It also appears to be cross-domain
(addresses AND names). However, it would appear to be a largely ASO issue,
since it directly effects IP address block policies (YMMV).
If one wants to make MAPS-like functionality a part of the Internet, at
large, then that's where one might go. Clarify your thoughts, write them
into a proposal and bring it to either the IETF, the ASO, or both.
Understand that much of the process is still being defined and there is a
serious lack of participation from those that should participate. But, it
may still be your best approach.
I work in the ICANN/DNSO and have no serious connections in the ICANN/ASO
and only slight contact in the ICANN/PSO.
