Disagree.
It's a great tool for vendors of used (stolen?) goods. As for the 10000 Sanyo serial-numbered items...yeah, I'd search through the list. But the program could list them in order. I think it's a great idea.
There are fundamental dynamics surrounding new ideas...and those who would execute them. This is from business training, and business books, and business experience: certain people immediately spend thought and energy on coming up with all the ways to say why something WON'T work (that's what you're doing, here), while others spend just as much time and energy figuring out how to make an idea WORK.
Not to say you are always this type, of course, just saying that that is the role you're playing here. IMO.
i have a bridge you might be interested in..
My daughter's friend's boyfriend (got that?) stole the girlfriend's stuff and sold it on ebay. The girl saw the stuff (she could read the serial numbers!) and had the guy busted. He had some other stolen stuff, too. Nice guy. So, I guess I could see this working in some cases, anyway.
