Assuming the actual register stays, what resources are out there for a barcode implementation? FOSS on Linux, the ability to use a cheap scanner, datamining, and output in a useful format (OpenOffice spreadsheet?) are all requirements. The idea hasn't been pitched to the shop owner yet, so ease of use is probably more important than anything — but breaking out the programming books to work on parts isn't out of the question for me."
