I do, our webservers run it. ZFS with automatic snapshots has saved my ass quite a few times already. Sending incremental snapshots (for backups) to offsite location (another OpenSolaris machine) is also easy and efficient.

But, if linux had ZFS i'd probably use that instead.

FreeBSD has ZFS too. We've been seeing a lot of people migrating from OpenSolaris over the past few months due to Oracle.

I wonder if the OpenSolaris people would consider a merge? Ie, work on zones, any useful Solaris management tools, etc...

FreeBSD already has jails, so there's no point bringing in Solaris zones; but we're generally quick to bring in features from OpenSolaris. DTrace, for example, is available for the FreeBSD kernel now, and work is underway to make it available for FreeBSD userland too.

It's coming along.

Could you clear something up for me? If ZFS is so highly coveted (which I've inferred from recent discussions), why doesn't every operating system under the sun support it?

In a nutshell, the issue is that the Linux kernel which is licensed under the GNU General Public License is incompatible with ZFS which is licensed under the Sun CDDL. While both the GPL and CDDL are open source licenses their terms are such that it is impossible to simultaneously satisfy both licenses. This means that a single derived work of the Linux kernel and ZFS cannot be legally distributed.

FreeBSD has it, but it's been largely abandoned on Mac OS X.
