Use a gprs / cdma cell phone. You can never hope in hell to get a better price, availability and service which would be the exact opposit of any custom 802.11 device which a person has to carry merely to find dirctions that he may require occasionally.
Devilish thought.
I can just see thousands of liberated visually handicapped people roaming free in the city - and becoming totally helpless the next time some babu decides to shut down cell services because some cop discovers there is a village in Maharashtra named Pakistan Pada, and they fear a riot.
Essentially, any switch-based service is at the mercy of a central controller. I don't know how the wifi/rfid concept will pan out, but it has the enormous advantage of being unstoppable.
I do believe we are debating new ideas, not old ideas in a new wrapping.
