System.loadLibary() doesn't need the extension, but only searches in the
java path, or the system path env variable. Depending on your local java
provider, they may implement whatever they feel like. Although every "pure"
java developer states that loadlibrary() should be prefered to load()... it
fails enough to ignore it imho.

In theory, I guess not. From a practical point of view, yes. The application
needs ege to be aware whats happening (if only so it knows the movie started
playing, and stopped). Going further, one might need native canvas drawing
(to include the output in a player window), emulated button/mouse
navigation, etc...

I started making changes, but I am waiting for some feedback before I do
more (I dont want to duplicate work, and not sure what the current idea is).
