Nice. Have people tried it out with gcj, kissme or some other VM based
on GNU Classpath?

Which does not mean we cannot recommend using their implementation of
javax.sound as is on GNU/Linux systems if it just works out of the box
and has no non-free dependencies. Our current AWT implementation is also
depends on LGPL code (gtk+). The LGPL makes sharing some code with
people who are mainly interested in embedded systems more difficult, but
since tritonus depends on ALSA and/or ESD which are already distributed
under the (L)GPL this doesn't really matter.

If we want to distribute it as an integral part of GNU Classpath then
making sure that all code is assigned to the FSF is the preferred way to
go. But there are other ways we could package things.

As soon as I have tried it out (might take a couple of days) I will
contact them about how best to work together.
