Yes, there is no work around here, since an AuthUser is a resource,
and a resource pointer can not be kept without special care (ie
providing the AuthUser would require that we setSate(STATE, authuser))

The namespace is not a problem, since all state pieces are prefixed (a
convention) with the class that is responsible for setting the
state. The AuthFilter being generic, part of any of its subclass
contract is to provide that info.

In the case of multiple auth filters, you'll get the inner one,
yes. Note that currently HTTP doesn't let you put multiple
authentication on the same document (you can have one IP and another
basic, but not two basics, or a basic and a digest). If this were to
become possible some day, we would probably have to redefine the
semantics of STATE_AUTHUSER to return a String[] (I guess)
