Good luck, and stay strong. I think the demo you created was incredibly impressive, and I suspect a lot of people will therefore expect a
lot from this product. This is going to sound overly pessimistic, so please forgive me - but I suspect that, as time goes on - and it will, because to me the goals of this project seem
huge, and the problems you're attempting to solve seem hard - you'll probably cop a bit of backlash over the time taken, not living up to expectations, etc.
I hope that if that happens, you're able to ignore it and keep working on it anyway. Regardless of whether you accomplish your goals or not, I'll happily be throwing some money into the kickstarter and crossing my fingers for you guys, because the actual idea behind this is awesome.
