Financing / Crowdfunding : Product Placement in Independent FIlms by Richard E Watts

If anyone has any experience with arranging product placements I'd like to hear about it. We've done some small projects that has used them and it's worked out pretty well but I'm interested in hearing some other points of view. It seems that it could be utilized on a much larger scale to help fund independent films but I never hear about it. We're in the development stage of a digital feature project titled The 4th Letter of Ponce de Leon. I'm pitching some vendors right now on participating. In particular I think it's an excellent way for new designers to introduce brand new products. Of course, vendors with well-established products use it continuously. Just watch an Adam Sandler movie. Ideas? let's hear them..
