We are moving targeted policy to cover all non-userspace processes in 
the future, (RHEL5).  I am not
sure what you mean unsported.  If you have layered products providing 
their own policy, that will be
supported.    The thing that is not supported, except through 
Professional Services, and picking an choosing
which policy you will be running and modifying the existing targeted 
policy.  If you modify existing policy so
that it breaks the machine, Red Hat Support is going to have a difficult 
time diagnosing the problem.  We
just want to avoid that.
