Just a quick shout-out to Roderick: Thank you for the paper reference. It's probably perfect for my needs, but I've been a bit busy, as of late. So no papers, regardless of year written. One of my favorite references is Thompson's "Reflections on Trusting Trust" so I'm hep to your SuperFly-Era ways. No dateism or ageism from this child of the 60's. -jrh
