Have wrestled with the same idea and variations of it for years.
As others have pointed out, getting local businesses to use it will be problematic for a number of reasons. So, another variation would be to turn it on its head and make a 'I want something' system - something for people to signal what they're looking for - and make these requests available to any local business to watch/review and respond to. The kicker would be they'd have to respond pretty quickly.
If I'm looking for X - I may not even know exactly what X is - but I describe X as best I can - few words or exact UPC or whatever - along with my city/location/area, then start getting response/offers back to me within a few minutes. Perhaps I put a time limit on it - I need to know in the next 30 minutes. If I get, say, 3 offers back telling me store ABC has it for $y and store DEF has it for $z, I can go to either location, or contact them back and arrange a deal, or just ignore them because it's too high.
It's not the instant gratification tied with realtime inventory propose here, but it's a step in the right direction. And once you have one half built, and see the signals/searches people are putting in, you can more easily convince local retailers to participate. Perhaps they pay a subscription to review a feed, which they can tie in with automated systems, or they pay a fee on a per response basis (almost like a slowed-down turn by turn google adwords).
