I'm working on an independent Java bindings project, which has the
advantage of implementing all FUSE 2.6 + the extended MacFUSE 2.0
operations (getxtimes etc.).
You can try it out for yourselves:

http://hem.bredband.net/unsound/jfuse/jfuse-0.1.tar.bz2 (compiled
libraries, javadoc and Java sources)
http://hem.bredband.net/unsound/jfuse/libjfuse-0.1.tar.bz2 (JNI library
sources)

There are two example filesystems included:
- HelloFS (org.catacombae.jfuse.examples.HelloFS)
Simplest filesystem you can imagine.
- TestFS (org.catacombae.jfuse.test.TestFS)
A filesystem that I'm using for testing the library. It is writable,
all contents are stored in memory, and it seems to pass fsx tests. It
also implements the extended MacFUSE callbacks for changing chflags and
the extended time values.

It's in a very early stage, so some feedback would be much appreciated.
Extended attributes have not been tested or considered at all, so those
callbacks may need to be modified in the future.
Mac OS X compiled code exists for i386, x86_64, ppc and ppc64 so any JDK
1.5+ should be usable.
