I've been toying with this for a while and was inspired to finish it for my buddy Matt "Mythmere" Finch's Swords & Wizardry Appreciation Day recently. It's a Psionics system that is completely unlike 1974's era published rules for same. Obviously, it's written to be compatible with S&W but can be used with any OD&D compatible game with little or no work. Take a look. After a short while and pending feedback, I'll make a PDF available via Wobbly Goblin's drop-box.
