I can't give any specific timelines as to when that sort of functionality will be available, unfortunately, but keep an eye out for release notes when new versions come out, and make sure to keep checking back here as we'll definitely make a big fuss on DevCentral about it. ;)
As for the auth commands you can check them out here:

The functionality isn't precisely what you're looking for, but it's a way to work around it for now as long as you're talking about accessing data from an auth type source, like LDAP or RADIUS.
There are a few examples in the CodeShare as well that are doing this kind of trickery, I believe. If you have trouble along the way or getting started, holler and I'll try to be more specific.
