Personally, I think it would be neat, and even without needing to fix my laser unit, I've been interested in poking around the insides of my drive lately, but to be honest with you, it's just not something I would be interested in paying for. I'm leery of eCommerce to begin with, and it's just a matter of time before a techically savy fan releases the same thing for free.
Just my opinion, but good luck with your ventures.
