I've been using it just for the /usr/ports on my i386 laptop for a while
(dual core T2300  @ 1.66GHz with 1 gig Ram:)

([EMAIL PROTECTED])$sudo zpool history tank
History for 'tank':
2007-04-11.10:45:56 zpool create tank ad0s4a
2007-04-11.10:46:35 zfs create tank/ports
2007-04-11.10:47:06 zfs set compression=gzip tank/ports
2007-04-11.10:53:29 zfs set mountpoint=/usr/ports tank/ports
2007-05-11.09:31:37 zpool scrub tank
2007-08-08.12:31:44 zpool scrub tank
2007-08-09.14:51:52 zfs set atime=off tank

with no issues.
        With appropriate tuning I also now run my home server (personal email
server, samba and nfs server for music/video/documents) which is again
i386 with 3 gigs memory with /usr and /var on zfs mirrors.

for this I did have to set
kern.maxvnodes=40000
vfs.zfs.zil_disable="1"
vfs.zfs.prefetch_disable="1"
vfs.zfs.arc_max="83886080"
vm.kmem_size_max="536870912"

for it to survive a portsnap fetch && portsnap extract without running
out of kernel memory. since then its run with no issues. I'm told that
FreeBSD/amd64 is a better choice for zfs though as "with a 32bit kernel
you are more likely to experience problems with KVA shortage than you
are RAM shortage when using ZFS."
Also see the thread starting:
http://lists.freebsd.org/pipermail/freebsd-current/2007-June/073972.html
for reports from people using it (back in zune true but its only going
to have improved since :)
