It sounds like you might want to implement an offline app instead. There is browser support in most browsers for appcache to make all your assets available offline, and there is the javascript call navigator.onLine that will tell you if you are offline or not. You'll have to create and maintain an appcache file. There is a gem that handles that, but I ended up just creating an appcache controller and serving it myself.
This is quite a fundamental architecture change, though, so you might be too far along in development to do it. You could create a small sample app to prove the concept, then drag all your existing code into it. See http://railscasts.com/episodes/247-offline-apps-part-1 for an introduction.
