I'm curious if anyone else out there has done this successfully?  I doubt
anyone at RH has ever even tried it.  It sounds to me like you're outside
the scope of what a person can or should do with this software.  At least
reasonably.  It may be technically possible to make it do what you want, I
don't know, but I doubt it would be easy or pretty as you've shown.
