I kickstart (read: purchase) a lot on Kickstarter. The one main gripe is not having a project meet deadlines and or not coming to fruition at all. Leaving everyone that helped fund a project at a loss of funds.

I'm putting together a personal project on kickstarter myself and it is pretty straight forward. The difficult part is coming up with a delivery date and sticking to it and delivering. In your project I'm sure there are a few variables to account for as well.

IMHO, communication is key before and after a project is funded, and having a clear goal and product availability to those that fund.

Also, if choosing this route, you may be able to get everything you need done for manufacturing for most or even all your products based on your poll above.
