Homebrew PCBs

I just had an idea of a better PCB generation system. It is still in the 
works, but may be a great solution.

There is the photo-resist method that needs darkness.

There is the Toner Transfer System that I use a lot. But I find that I 
am always touching up traces, especially the fine ones.

One person figured if they can print directly to the PCB using a laser 
jet, but the stiff board would not go through the rollers.

What if I can come up with a flexible material that can be printed to 
directly a positive image and then etch? It would be able to go through 
laser printers without a problem.

I am building up some samples to test, but would this list be interested 
in such a product?

Oh, to stiffen up, just add a piece of fiberglass to the back. Which I 
can make as well. Would you be interested in this method? How much would 
one be willing to pay for the materials for a 2"x2" size of board - 
granted a larger one would be possible as well. In fact, using a legal 
size copier would allow one to print up a 11" x 17" circuit board.
