Ditto! Implementing what is suggested would be around 20 lines of code. We've done the same for SeaDataNet to get their vocabs within their namespace such as

Subject: Re: [CF-metadata] Web reference to a standard name?
In theory, MMI can support that approach (redirecting cfconventions.org, ideally transparently). (That is, I worked it out in my head once. Haven't actually tried it in practice. I *think* it's "just a simple matter of programming". ;->) I think that's the best combination to support both appropriate branding and the kind of support a "full time dedicated" repository can give. Roy's server perhaps the same. (But not both at once!)
Just to be crystal clear, the places where you have '16' could also have 'current' (if I understand correctly what Roy was saying about their server), and the mmisw one could also be served with a particular version ID (analogous to the NERC example).
If there is someone on the CF (or other) team that wants to play with us on the 'simple matter of programming' part, that would be a collaboration we'd be happy to encourage.
