title: RoR + SMS: Rails web app architecture to send/receive SMS?
body: <p>What web app architecture works well receiving/sending SMS text messages? By "architecture, I mean specific architecture, not generally, such as MVC.</p>
  
  <p>Background: I'm building a web app that receives queries from/sends answers to cell phones. The app design (and business model) expects to communicate with cell devices via SMS text messages. IOW: There is no MVC web page "view". The cell phone screen is effectively the "view".</p>
