You should be worried if the idea is patentable. You don't say whether you were the teacher or a class member. You say there was no operating agreement, but were there rules for participating in the class as to the ownership of the information? What you can do is build up your idea so that it is worth billions and wait for the lawsuit form the guy who wants to be bought out. Or you could pay him a relatively small amount for a release. Call the Idaho State Bar for a referral for an attorney to help you figure out (1) if you owe anything, (2) does the guy have a colorable claim, and (3) if yes to 1 or 2, prepare a proper release so it does not come back to haunt you.
