This reminds me of how price scanners are now placed around retail store chains. I can't remember ever feeling like it was a big pain doing without them when they weren't prevalent. It was inconvenient when a shelf was missing a price, or when I forgot how much an item was once I changed aisles. But it wasn't "hair on fire" important because there was no solution yet. Nowadays, of course, when I need a price check and the nearest scanner is 20 feet away (if there is one at all) I'm feeling quite inconvenienced.

So to answer, I wouldn't abandon the idea until I had bounced it off of several customers and potential clients. It could be solving one of those problems we never knew we had.
