I had a CueCat with the intent of installing the open-source driver, never got around to it. There was a much-better device that came later, the Hiku. It wasn't free, but it was basically a WiFi-enabled battery-powered barcode scanner designed to manage your shopping. You'd scan the barcodes of items as you tossed them, and it would automatically add them to your shopping list. The hardware was way ahead of its time, even now something with those capabilities would cost something like $500 from Symbol. It even had a microphone so you could just record stuff to add to the list if it didn't have barcodes. Even after the company folded and the backend was shut down, turning the reader into a doorstop, the app still worked for several more years, and I kept using it for shopping lists because it synced in real-time as my wife added items to the list while I was shopping and ticking them off.
