There's a lot of speculation about what's running where. This is, as people have thought, a web based app. The UI is entirely built into the page, so in order to change that, you'd have to build a custom parser to modify the CSS and javascript to suit your needs. It is not running on a server they own - both the iOS and Android servers are running on separate Google App Engine domains - appspot.com. For those developers who've used it, you'll recognize why there are problems with stability and speed on this platform. I don't want to post the details, but knowing that much, you should be easily able to figure out specifics if you have some technical aptitude.
