Houston thinking about using WiFi parking meters for citywide wireless network

So the city of Houston has this crazy idea: as long as they're adding WiFi to the city's parking meters for verifiying credit card info (yes, that means no more fishing for quarters), why not open up the WiFi network so that the general public can get online, too? As long you're spending money on building out all the infrastructure, sorta makes sense to add a citywide wireless network, right? Right now the city is in the process of selecting a manufacturer for the new parking meters, and once that's completed they're going to start looking at the feasibility of creating a public WiFi network and figuring out how they'd add coverage for the parts of town where there aren't parking meters.
