Request For Comment:
The Java applet presents a few limitations. First, it is difficult to support in multiple browsers (Micro-cough IE). There is the security sandbox to consider (signing), installation of the JVM, temp files, hard-coded User Interface, and who-knows-what-else.
I imagine the Index will work as it already does (a Java Application).
I am not familiar with LiveConnect, or the kind of programming involved to do what you described, but I would like to express my concern regarding portability among at least the following three platforms: MS Windows, GNU/Linux and Mac OS X.
If what you described works the same on the three of them I don't have any issues.
Based on test results, I have dropped this idea completely.
