I agree with you there, but something occured to me. Is d.net not
trying all the possible keys in a logical order ? I seem to recall
reading that somewhere. Anyone can reasonably assume that we'd turn
in the correct key were we to find it...
So, by these assumptions, all these guys looking for the key at
random could limit their search to the bit not yet done by d.net
couldn't they ? I may have missed something on the way, but this
seems to follow to me, and it would put there chances of happening on
the right key up quite a bit ! :-)
