Tweeters,

Thanks to all who responded (privately and publicly) to my request for
information. I have not had a chance to follow up on any of the leads yet,
but they alll look very useful and promising.

With apologies for this impersonal way of thanking all respondents, but I
got a total of 16 reactions. Way to go tweeters!
