This sounds pretty interesting! Will Synedra be under an Open Licence like subversion or the GPL?
Is the Synedra architecture documentation available online?

Yep. Thats fine with me. I think the subversion java/gui project has nothing to
lose with this but a lot to gain...

Some remarks about the design:
right now the java/subversion implementation will not be 100% Pure Java.
Instead, there will be a JNI layer between the public availabe classes and
interfaces and the subversion API libraries. Its not an ideal situation for me
but the one with what we will get the fastest results. Maybe later we will be
able to implement all of the client side in Java (which should not be a problem,
otherwise the designers of the java/subversion library are to blame).
