I'm so glad someone asked this question. My thing has been that I would like small businesses compete with the likes of Starbucks by setting up free Internet access. I think there's enough room in the margins to pull this off, and it would give smaller shops a real crack at topping the big guys. Where would you go to drink coffee? Free access, or $3 for 15 minutes (which I think is way overpriced)? I discussed this with James Duncan Davidson, and he wrote a good article that I think you'll like: Easy 802.11b for Small Businesses. Check it out.
