I mentioned in the comments to the Psionics - First Thoughts post that they make me think of Psychics and Bene Gesserit more than Magic Users. Taking that a step further… here's a Bene Gesserit class that's compatible with the system we're using for our Weird West game!
The Bene Gesserit abilities seem pretty close to many of the Psionic Disciplines. Those will need a bit of fine-tuning like the Attack and Defence Discipline did - but the basic foundation is there.
Bene GesseritThe Body Weaponry ability would be pretty close to the Monk Class Martial Arts ability.

This might be a pretty tough class compared to some of the others I've posted... Then again, I think the idea of balanced classes in RPGs is pretty over rated anyway. ;)
I think both the book AND the 1984 Film version of Dune are fantastic. The soundtrack is outstanding, and I'm glad we're going to see more sci-fi movies with popular bands doing soundtracks in the near future. :)
