Yep I was thinking about that. I could implement the same approach I'm
using in BeerCloak, but only if I were sure I'm not doing it in an
obsolete/deprecated way. I've heard that authorization for REST admin
resources has been revamped recently; could you please take a look at
BeerCloak just to make sure I'm doing it the right way?

Thanks,
Dmitry
