> This already exists, so whatever objections you have must have already been surmounted. There's a huge difference between some fly-by-night operations working in this model already existing and a company the size of Wal-Mart taking it on. Additionally there's a huge difference between a person coming in daily as a contract employee and a company like Wal-Mart recruiting its customers at the checkout. The difference is lawsuits and liability when something bad happens. If it's a small company there's not so much assets to go after. If it's Wal-Mart the ambulance chasers will come out of the woodwork.
