-Since flashing the device each time to configure WiFi was a pain I added some code that creates an Access Point and allows the user to configure the wireless network via their mobile device. I created a slimmed down version of [base css](http://getbase.org/) to style the pages served by the ESP8266. I used an interesting hack I ran across, it serves the WiFi configuration page for any requests that result in a 404(Not Found) HTTP code. Mobile devices apparently try and hit some specific page for login when they connect and don't have internet (like you seen in hotels or guest networks) and by returning the configuration page for 404 requests it allows easy configuration no matter what page your mobile device OS requires. Once the device is connected a status page is available to check on your button and reset WiFi settings if necessary.
