I've just installed Leopard on my MacBook Pro, and was first disapointed that it only had read only zfs, but after checking out ADC that was solved :)
I also wanted to try out Time Machine and thought that I could place the backups on zfs, but Time Machine doesn't let me select zfs as a destination. Hopefully I'll be able to trick it somehow ;)
Update:
after Jeff Harrell's comment I read up on Time Machine
here
and here,
and as Jess says it uses directory hard-links, so that won't work with zfs. Bummer! :(
Time Machine saves time and disk space by creating hard links to directories. If I remember correctly, ZFS does not support directory hard-links, only file hard-links, like most filesystems. So it won't be possible to make Time Machine work with ZFS.

So hopefully Apple will develop support for directory hard-links and feed it back to us...

Hey just use Solaris Martin! With ZFS and a bit of basic scripting, you can take periodic snapshots and perform backups whenever a USB disk is inserted. Now just add some Compiz eye candy, and we're done :-)

I've new versions of each in the works, out soon, which adds a simple GUI to do configuration and packages things up a bit more conveniently too.
