I have already bought the right to use Jeroen's book
twice.

The issue revolves partly about in what ways I can
use this book.

I was able to convert the Rebel book into my own format.

Some things that are now possible:

a) Write a program that identifies which lines in my book
have been refuted by Jeroen in his book. This would effectively
void any killerline Jeroen has created before the public release
of Rebel Century 4.0.

Considering the Rebel book contains in excess of 370 000 moves,
this would save ages of autoplayer games.

b) Write a program that automates the autoplaying between
Jeroens book and mine. I could, for example, add a learning
function to my book that picks up lines we were beat with.
Alternatively, I could just save all autoplayed openings
to a PGN file, and build a book from that. I can enhance my
bookbuilder so it remembers which lines were played by
Rebel and gives them a higher weight.

This would allow me to make a book with all important lines
from the Rebel book, without ever copying anything.

c) I could go to Maastricht and wreck havoc among the other
amateurs by using Jeroen's book.

All of these are legally possible. By *current* regulations,
I understand the ICCA would not be able to prevent (c).

Jeroen has requested in private email that I do not do (c),
so I will not. My problem is now what to do with (a) and (b).

I will probably do (a), since I see no moral problems with
it whatsoever.

(b) is more interesting. I could do it now with autoplayer
games, and I would see no moral problems with it in that case.

However, I have moral reservations about automating/speeding
up the process by designing a book-only autoplayer.
