I would be surprised if this worked. From my understanding (which  
could be wrong, and likely is) FBSD's works with GEOM in a way, so I  
would doubt it would work. It would be an interesting test, but I  
wouldn't risk my data trying it.

OpenSolaris is stable, it eventually becomes the Solaris build, so I  
would run it (and do). I would check to see what build is considered  
'safe' though. I know a bunch of people that run it in production.

As for FreeBSD, as of 8 months ago (or so, whenever BSDCan was), the  
guy that ported ZFS to FreeBSD said he wouldn't run it in production.  
He said he hoped 7.0 would be production ready, but I am not sure  
where it's at.

I would do some research and or post to the FBSD lists (or just email  
him directly).
