I was wandering whether you have any plan to make your application an android-ish one. AFAIK android apps are java-based too, so probably (but I may be wrong, since I am no expert) it will be feasible.
That would allow djvu files to be read on all android smartphones.
As I said, I am no programmer, but I'd be an enthusiastic beta tester, in case.

I remember seeing a message on the DjVu forums about an android port. My cell phone is down right primitive, so I was not able to try it. I believe all that was required was creating he correct type of install package.
