That auth-token-middleware-for-swift code is now in the swift repository (https://github.com/openstack/swift/blob/master/swift/common/middleware/keystoneauth.py)

If it were really locked down and not changing, then I think maybe it would make sense to shift in there, but right now (especially with advancements in PKI/signed tokens) and looking forward to the V3 API set, I don't know that it makes as much sense. My intuition is telling me that it's not sufficiently unchanging and "common" enough to move into common, although getting it there is actually something of a goal.

I also recently mentioned the need to update the middleware for common caching in another thread, using beaker. Maybe we can split it out of keystone into its own project instead of putting it in common? But I'll need to pull in some caching stuff that I'll be prop'ing in to common anyway. I think we need a decision here one way or another for the long term. 

Side note: I'd prefer to not install all of keystone to get this one module, no matter where it is. But then again, moving this stuff all around is quite annoying to installers ;)
