Linux snapshoting is all at the block level, not at the filesystem
level.  This is a huge difference.  

Some of the problems with ZFS on linux is that the core linux people
don't like the layering violations in ZFS, since it tangles up block
level mirroring and device management into the filesystem, and visa
versa.  

I haven't had a chance to play with ZFS yet in any depth, but the
SB100 and disks sitting in the next cube are targeted for that
playing.  But first we need to justify going to Sol10 in a big way,
and we haven't yet. We're still running Sol8 generally, though even
that is going down as we move more and more to RHEL4 on newer compute
boxes.
