I wonder if Nexenta has added more/better support for IB? I believe
that Illumian 1.0 is finally out (after having run the Alpha for
years), and I know that they did have some interest in supporting IB
originally. If they have, then I would hope some of that support would
make it back upstream.

Mayhaps I have an email to send out ...
