This question is intended for larre-ga, who came pretty close with the
answer to Question 71041. I think that her answer (which you should
see) is worth the price of this question, thanks.

Thank you, Yorker. This price is eminently fair for the information I
was able to provide.

Good research turned up several avenues for me to pursue, and since it
wasn't possible to fully answer the original question, the researcher
graciously posted her work as an un-compensated comment. Because it
was so helpful, however, I have insisted on re-pricing the original
question and paying for the answer.
