Joe -
I e-mailed the link you provided and was answered almost immediately that he would NOT like a bunch of emails; that there should be NO petition; and that it is UNlikely that the book could be re-released in large print because of the unlikely sales prospects, etc; however, the 10th anniversary edition will be in a "clearer" text, although not larger.
He did say that the tapes might be re-released as CDs - something I wish they would have done before I bought the tapes. It is UNlikely that I will spring for another set.
