There's nothing inherent in the product which prevents you from associating
state with authenticated users. It's just not as useful because once
they're authenticated you'd probably be better off associating the state
with their user object.
I've seen a couple of examples of session usage, however, that mix user
state and session state... for example, in the ASP world (and I think in the
servlet world too), when a session starts and ends, you can associate an
event with it. So this allows you to use the session space as sort of a
scratchpad for use when a user comes in. At start time, you copy over some
user state to the session object (based on authentication information). The
user does some stuff, changing the contents of the session state. Then when
the session expires, the session end event is called, the state is copied
back to the user object. This is something that core session tracking
doesn't do because session ids don't expire.
There are also a couple of undocumented methods in core session tracking
that allow you to associate a session data object with a user's database
path. The reason that they're undocumented is because I'm not sure how far
I want the tendrils of session tracking to go. This is an area we need help
in, but it's probable that this information should probably be associated
with the user in another way.

Core session tracking is the same.
