Great work so far Mike, really like what you are doing! I know you have the ability to add an image to a keg (although as I write this my upload ‘failed’ for some reason… it said it sent you an error report), it would cool to be able to substitute another image for the keg image. Many of us home brewers have exotic tap handles that could be photographed and would provide the way to know which keg is on which tap.
IE, I don’t number my 5 taps, so knowing that my Guinness clone is on tap #2 doesn’t really help someone. Knowing that the Guinness is on the tap that looks like a barber pole…does. See what I mean?
