I've been using Cellera too - not that bad, but definitely not worth
$$$ in most cases.
I've been using SC+ZFS in a production for over a year now (first with
beta version). It works pretty good - I mean, it just works.

Not exactly...
All answers to your wish list is yes, with following
exceptions/notices
NFS - no problem at all, it will work with SC+NFS+ZFS
CIFS - if you're happy with samba - then yes. If you are after Solaris
native client - well, it was just integrated into Nevada so if you're
happy with Nevada...
iSCSI - haven't really use it, not in a production at least. By using
shareiscsi zfs property I guess it should work. I don't think
there's a special SC agent for it.
AD - not sure about samba
"Restriping data" - nothing automated yet. If you re-write data
manually then it should just work.
Migrate data between pools - not entirely online
Asynchronous replication - you can try AVS, I've never tried it.
Or you can go for zfs send -i
