Everyone has ideas, its the execution thta matters. If you get accepted, how will you turn your idea into a product and business? If you don't know, you're probably not ready.
Agree entirely... I know HOW to get the business running, I just haven't (yet) found the right person to help me do it. My advantage is that my tech needs largely already exist in other contexts so I know the tech exists and can be re-applied with some tweaking.
