While ham radio has flexibility and coverage advantages - don't forget that simply handing them out to your neighbors won't work. The operators must be licensed and must behave themselves on the air. Otherwise the repeater control operators must shut off the repeater.
A friend of mine, a real gadgeteer ham radio guy, set up all his neighbors on business band handheld radios. They had a pretty good network going. I don't know if the net has held together since his passing :-(
