Scott,
Just added both Audio and Video Trancoders Xugger based demos. Everything seems to be working fine.
Another note of interest, is that it might be possible (not tested yet) to force the wars to be loaded in order of apperance in application.xml file. For that to happen we only need to add the tag:
<initialize-in-order>true</initialize-in-order>
If this is true, then we might not require to specially package the loading of the default context on its own specific jar.
