That is great! I tried to get that working myself but failed as Eclipse 
3 was very new at the time. If that is actually working for you it is 
really good news; it would give
me a way to bundle up the imageio-ext Dlls used for MRSID and others. 
This is really nice way to do things; it is how SWT works for example.

We can always measure to see if there is a performance hit.

Well we could also switch udig over to your "jai-libs-win32" plug-in (or 
whatever it is called), and then the instructions for getting webstart 
to go would be easier.
