I think it is easy to make an argument that permanent memory is written
material. If you store a openingbook on your harddrive it is written material in
my view. Its there to read for anyone with a PC to connetc to the HD. :-) And as
such against the rules!

So what it boils down to is what kind of material you consider the openingbook
on your PC to be.

In the "old days" the programs where so weak that we allowed them to "cheat"
with a openingbook. Without it the programs would play to stupid chess. Now I
think it is time for the programs to do without.
