For now, all integration with Unity is going to be slim, meaning that for now it is going to be a bookmarked app. As I learn more from the API, I might even be able to set up notifications, menu options, and more.
If you want to take a look at the Unity Web Apps API, go here. It is actually very simple, and personally I found it odd that it wasn't hard. You do have to put this in between <script> tags. Right now, many popular websites support Web Apps integration, such as Twitter, Facebook, YouTube, GrooveShark, and more.
