Among friends, and mostly, my brain. I trust my own brain above most other brains... it's worked out pretty well thus far. I've went over it with a couple "close associates" who have the proper credentials to at least listen to their opinions, and they haven't found anything obvious. But yeah, if I were to pursue it the first thing it needs is a more thorough incentives analysis. No plans at present to make it available publicly though.
I'm not saying you have to publish it for the world to see but you need to go beyond your own brain, however bright you are. We all tend to think our own ideas are great .....
Haha. Yes that's my point. That's why I'm waiting for the time to properly pursue it, hoping someone else will come up with it in the meantime. We'll see. If I never get the chance, I'll just take the time to publish it instead. We're not there yet, I'm still thinking I'll have time to develop it in a few months. I only woke up with the final puzzle piece of the answer (I think!) a few weeks ago.
