I'm afraid most people don't have the energy/motivation to think as
deeply re: these issues as you have, which is likely a symptom of the
malaese (SP?) which has led us to the current state of affairs. We
elect officials, give them the responcibility to think/answer these
types of questions, and only get intrested when their decisions
directly effect us.
Most of us go about daily lives w/o considering these questions and
don't have the needed background when it comes time to make the decisions
(like voting) when we have to. I don't know the answers, but its nice
to see people like you forging ahead:) and forums like this within which
more can share your expertice and energies.

ps. I'll likely go back to lurker mode, but THANKS for that last set
of questions; well thought out!
