I'm using native ZFS (http://zfsonlinux.org) on production here (15k+ users, over 2TB of mail data) with little issues. Dedup and compression disabled, mind that.
Dedup especially is a major source of trouble, I wouldn't recommend it for production just yet.

I can't imagine running any kind of performance critical app on linux using fuse! There is a native ZFS port going on, but I don't know how stable it is yet.

If I/O performance is a concern, you may be interested in ZFS and Flashcache.
Specifically, ZFS' ZIL (ZFS Intent Log) and its L2ARC (Layer 2 Adaptive Read Cache) ZFS does run on Linux http://zfs-fuse.net
I'm using NexentaStor (Solaris, ZFS) to export iSCSI-LUNs and I was thinking about a SSD based LUN for the indexes. As I'm using multiple servers this LUN will use OCFS2.
