> Do you accept? If not, why not?

Almost no one on HN will agree. (I predict.) Ideas are easy. Even I have ideas. Doing something with the idea is what counts. That starts with programming, but also involves selling product and running the company. So unless the idea-person has a great record of implementing great ideas and good exits people will be unwilling to lumber themselves with a lot of work for so little return.

Maybe yes. Really depends of what can be "boatloads of money" and the current appreciation of realize it. Supposing I have nothing better to do, and that you are a good team mate, I will certainly accept. This means your proposition will be more valuable to a fresh greek student without green card than to an experimented coder at Google.

Not the same game, as there is no cost (time, money) in the original idea to compensate for. In your version you have to work to achieve a goal.
