Just to clarify, what Brantley has is his own copy of the Bill Broderick letter, printed from the PDF file. If it's valid, it is effectively unrevokable anyway as it grants permission to use and distribute freely to anyone as long as credit to Caldera is maintained. But as long as nobody has a signed original it may be messy to prove that it's valid. On the other hand, I assume that if it can be shown that Caldera were aware of the letter and behaved as if it were valid, there are no secrets left to protect in V7 or 32/V. On the other leg, however, that letter doesn't open up System III. Norman Wilson Toronto ON
