Implementing these shouldn't be too hard given the rewriting capabilities of pynac. The problem is to provide an intuitive user interface. Francois Maltey had some good suggestions for this. Putting these up on the wiki has been on my todo list for quite some time, but I never managed to find the time. I'd be glad to forward the relevant emails to anyone interested in taking over this project.
