Homebrew PCBs

Now that I can print single sided  boards, I think I've found a way to print double sided boards, with excellent registration, in a single pass. This will need more than a simple hack, but I'm pretty certain it is doable.

I'm considering the commercial applications. Is anyone on the list knowledgable enough in the field to provide some expertise and thoughts as to the commercial viability of such a product? I would especially be interested in someone who is interested in partnering in the project. BTW, I have several successful inventions on the market and have some financial resources to pursue this if it is viable.
