Thank you. There's something similar to Xnest.h called Agent.h in the
NX sources but it does not seem to solve the problem completely. The
problem is that XKB exists in the server and in the lib. Still
investigating.

This looks promising. However, it means touch a lot of places so I'll
try to solve it with the other suggestion for now.

Thank you,
