Yes! There's a few bugfixes in master that are making their way into
Luminous, but Luminous has all the features at present.

In principle probably. I haven't tried it and I don't really know much
about Keystone at present. It is hooked into the various
IdentityApplier classes and if RGW thinks a Keystone user is a 'user'
and you supply whatever RGW thinks its username is, then it should
work fine. I haven't tried it, though.

If you want to give a large number of users the same permissions, just
put them all in the Principal array.
