But IHMO the way of implementation the module concept is bad. I think the
modules should be self-running programms and they use shared memory for
communication. This will have this advantages:
- better scaling on SMP-machines
- when a module crashs, the application will continue - without the
functionality of the crashed module
- much less name space problems
- Debugging can be done much better
- LibGGI3D can be much easier ported to other platforms
- modules can be developed and tested indepently from the developing of
