I am very pleased to learn that shortly (a year or so) after Sun's opening of Solaris under the CDDL open source license that communities outside of the Sun/Solaris community are truly seeing benefit. Pawel Dawidek announced yesterday that ZFS is now in FreeBSD HEAD and will be available in 7.0. This is very exciting news. We use ZFS and many of its advanced features extensively here at the $DAYJOB and I can say with authority that ZFS is damn cool juju.
We manage quite a few FreeBSD machines (in addition to Linux and Solaris). It's good to know that some of the elegant solutions we've deployed on Solaris leveraging ZFS will now translate well to another platform we work with.

In your copious spare time, could you elaborate on those elegant solutions? I, for one, would read with interest.

Well, https://labs.omniti.com/trac/zetaback is one of the things. This tool provides pretty simple backup (full and incremental) and retention for ZFS enables hosts throughout an enterprise.
On Solaris, we use ZFS to migrate Zones from one box to another and have only a few seconds of downtime (across datacenters). I'll note that this can be done on most OS's if you have and enterprise block-level replication system in place. ZFS's incremental sends allow it without foresight.
Additionally providing developers with individual read/write access to systems with large space requirements by using the ZFS clone and promote stuff (basically copy on write copies).
Most are techniques, Zetaback is the only one for the Zettabyte File System that we've formalized into a "tool."

have you heard/seen any progress of getting ZFS running on linux?
when I looked there was a project trying via FUSE, but it looked pretty quiet
