Best of luck to you in reaching S. Woz ;o)
As I recall, Bob has mentioned something about Apple's "fanning of the
flames" with their RoHS propaganda: Maybe this'd be a wake-up call for

Anyway, I think found him for you on Fundrace. Here's the link:
http://fundrace.huffingtonpost.com/neighbors.php?type=name&lname=Wozniak&fname=&search=Search
Did this before to target the CEO of one of the nation's largest grocers
for a presentation. It was a direct hit. If you can, send something on
company stationery...
