And let me add that you should not let person B resell your omni as part of his product X. The fact that he sells X for more than you sell the omni does not repay you for your time or idea. You sell one copy to B for ten bucks, and he sells a hundred copies of it, adding ten bucks to the price of some cheap prop to house it? Not fair to you. Let him get a fair price for his prop, no more, no less. If you set a price low and fair enough, B can sell X as a housing for the omni at a low and fair price of his own, pointing his customers back at you.

Let me say that less confusingly. It's like you're selling a figure and you're happy that other people can make money selling textures for it -- but you don't let them include the figure with their texture. Why should you?
