I've done it. I have been doing it for months. It is just that you guys don't like
java and as such my solution will neven be included.
Look at my afroapi distribution. It has automatic loading of required code and even
allows for loading code during page usage.
eg. I have a Cell object that can contain a cover to stop mouse events from reaching
the document. It only loads the mouse event code if the cover layer is needed. If my
code does not ask for a cover layer, the mouse code is not downloaded.
