I agree with Udo here.  Securing the channel between component/services has
really very little to do with Authentication/Authorization, and by
"Authentication", I mean in the user-centric sense, not the SSL "trusted"
sense (with "trusted" keys and such).

Whether a user can or cannot do something (in other words, is "authorized",
or allowed to invoke an action, given an ACL) is a function of the action
being performed and the privileges/rights that a user has been granted.
That is independent of whether or not the channel has been secured.

I also agree with Kirk that HTTP should perhaps be renamed to WEB.

Finally, while SSL is usually a cause to reboot the system, Auth has no
such restrictions.  I could easily change Auth credentials of a user (e.g.
revoke privileges) at runtime.

My $0.02,
