I don't think it is so easy. The question is whether your work should be
considered "derived work" of GNU Go. If you only use the standard GTP
commands, then it is probably not. But with the GNU Go-specific GTP
commands, you can get quite deep into the engine internals. Then it might
be less clear.

For example our debugging GUI view.pike might very well be considered a
derived work of GNU Go. (It would not work with any other engine at
all.)
