Palm Barcode Shopping-list

There are a lot of shopping list applications available for the Palm (haven't tried any yet). The input is the bottleneck. It is easier to scan the barcode of an item that you trash in the kitchen, just like the guy on the website icepick.com does (you can see on-line what is in his garbagecan). What is missing is a barcode scanner that can be attached to the cradle side of the Palm (the springboard-slot on my Visor is already full with my VisorPhone). Something like that IR- thing to turn your Palm into a remote control. I see shop assistants using a similar kind of barcode equipment for stock inventory. The scanner on the Palm would create a record in a database for each new barcode. Each record can be named manually, with more information than the obvious, like: "sister in law is allergic to this" and "great mix with that .. drink", "barbara's addiction", "it looks great but it tastes awful!" etc. Records can be linked together in a receipe. The records can be beamed to other Palms. Just the barcodenumber if you are only giving your shopping list to a shop assistant or the whole record with references if you are swapping receipes with friends. When you are syncing with your computer the barcodes translate into an order for on-line shopping. It also allows for associative shopping. You see beautiful tomatoes for sale, scan the barcode and your receipes of great things you can do with tomatoes appear. You can choose the one for which you already have most other ingredients at home according to the stock inventory in your Palm.
