Oracle holds the copyright on much of OpenZFS. They'll have to agree to relicensing it first. With Solaris dead I'd generally agree that it's a little pointless to keep it incompatible. They might as well just place it under something like BSD or Apache 2, that should keep the FreeBSD and Mac OS X ports happy as well as opening up the possibility of inclusion in the Linux kernel. With Oracle Solaris dead, I think there's even a case for Oracle's bottom-line: they could start including ZFS with Oracle Enterprise Linux and boast about all the advantages of using it there.
