Ask HN: How to monetize unpatentable idea?

I have been sitting on an idea for a few months which is quite simply an extension of already existing functionality which is basic to most programs. This is one of those "doh!" things where people will wonder why nobody had thought of it before. It will add intiutive functionality, make things far more accessible, and probably have far more uses then I've thought of. It will also have no problem garnering tons of press. I have a working prototype, but that is irrelevant. Once I release it, the idea will be picked up and incorporated into everything. While it does require some coding, it is really that simple.

The question is, how can I monetize the idea with a general implementation (or any way at all)? There is no way to make ad money as this will not involve going to a website or any possible ad placement at all.

Do I need to form an llc or something, release the technology as say a free extension to one program, and then sell the company whereupon some corporation can then claim they "bought the technology?" I'm really at a loss here as I am terrible with people (which I'm fine with) and do not have any social or business capacity whatsoever. I have no prolem spending a few months writing a freely useable extension and building a website for it, but I do not want to go into business. I just want to release an implementation and sell the company which I released the product under. This is totally feasible as I've seen corporations license similar, but far less useful technology which is not patented, and which they could have hired a team to incorporate into their own programs instead of licensing it. The point is, I'm not going into business. I sat in a cube for a long time and am now going to school and pursuing my own research projects which is what I'm going to continue doing regardless.

Any suggestions, advice, books, help, etc.. would be greatly appreciated.
