Right, there are still no fuse kernel modules or libraries in illumos.
When some implementation is "ready" (definition TBD) then it
would be reasonable for someone to propose integration.
(And I hope it might be based on my science project, but
if there's another that makes it to "ready" first, that's OK:)

The fuse library in https://bitbucket.org/gwr/illumos-fuse2a
is 2.8.5.  I presume the changes between 2.8.5-2.8.6 are
modest.  They might be unnecessary in the above code
because "fuse_lowlevel" is not included, and much of the
original libfuse code is not used in this implementation.
(Read the intro on bitbucket for why that is.)

If someone wants to update the libfuse used in the opensolaris code,
that should not be terribly hard.  That implementation uses the typical
"fuse kern. channel" interface between the kernel module and the
user-level library, so the library is not heavily changed from upstream.
