I have a couple of thoughts related to this. 1) Not only can the applet inject javascript code into the browser, but it can also inject SAGE code into a worksheet. When a given applet launches, it can automatically inject code into the SAGE environment on the server which can be used by the user to interact with the applet. For example, a graphing applet might inject an object called cgraph into the worksheet and then the user might type the following into a cell to view the graph on the applet: cgraph(x^2, 0, 10) cgraph will know how to communicate with the applet it came from and each applet can even have its own unique protocol using this "proxy object" technique With approach, the applet code will be very loosely coupled with the SAGE server code and applet development can occur without having to coordinate with the SAGE developers very much. 2) It should also be possible for the SAGE server to inject a data file into the applet that tells the applet what kind of GUI to create. Also, JavaSE comes with a javascript interpreter. Therefore, javascript can be injected into the applet from the server so people can create their own applets using Javascript and then the scripts can be saved in the notebook and used as needed. This might make it easier for people to create their own custom calculators and other applets.
