proposed response to Wolfgang Laun

Gary was kind enough to draft a response to WL's Last Call comment.  I
added a header/footer.  Please look it over; I guess we'll send it
Monday if no one has any comment.

(Chris, have you made any progress with the other LC comments?  We
wanted to try to close the loop on each of them by Tuesday!)
