Basically it is a program that can scan barcodes via camera and through a bluetooth handheld scanner. Pull information from a free lookup service like Biblio.
Pull prices from Amazon (they offer this service for free)
And create a database or comma delimited text file of the inventory/catalog.
Too complicated for me but after seeing some of the complex programs created here I'm sure someone can do it. Not asking for someone to do it for free. Would be willing to either pay or work out a marketing arraignment.
