Yes, this. Regardless of length of experience with it, I suggest
having a good read through the entirety of
http://www.kernel.org/doc/Documentation/filesystems/ext4.txt to check
the data integrity options. IIRC they differ from ext3 in places.

It is nice - the iSCSI is especially useful, IME - but requires a
separation of your storage systems from your non-storage (e.g. web,
DB, etc) systems if you require Linux environments for that second
group.
Also, unless you go the NFS route, you'll need to layer a Linux FS on
top of the exported ZFS block devices /anyway/, so you'd still need to
choose which FS to use.
FWIW, I'm finding ZFS-on-opensolaris/nextenta => iSCSI =>
ext4-under-KVM to be a decent solution. YMMV.

Nope. Not production ready.
