Of course, one could also examine RFC 3514 for some ideas as to how to implement such ideas. :-(. As others have said from different perspectives, if one can clearly differentiate between Good and Evil or Clean and Unclean and get universal agreement about the boundaries, then many things become feasible. Unfortunately, the quest for such boundaries, and debates about them, are, depending on which sources you believe, eight to 12 millennia or more old. Perhaps it will be resolved in the next few years, but that would be truly surprising. john
