I don’t know squat about whether you could actually sell this, but here are my two cents: Some products ideas fall into a category I call “Just Do It”. This is probably one of them. It sounds kind of cool. It’s not going to be all that difficult to implement. You have the time to spend on it. Basically, there isn’t enough risk here to worry about. You could spend a lot of time trying to figure out if this idea is any good, and at the end, you wouldn’t really know. Alternatively, you could spend the same amount of time implementing this idea, after which you will have the opportunity to really find out if it’s any good.
