A recent discussion on the lkml examined the possibility of a Linux implementation of Sun's ZFS. It was pointed out that the file system is released under the GPL-incompatible CDDL, and that Sun has filed numerous patents to prevent ZFS from being reverse engineered. Max Yudin pointed out, "according to Jeff Bonwick's blog Sun issued 56 patents on ZFS, but I have no idea what they patented. Sorry, binary compatible ZFS reimplementation with GPL license might not be legal."

Actually, Solaris has had an excellent albeit traditional volume manager for *years*. Until Solaris 9, it was an unbundled product but starting in 2002 it was bundled with Solaris.
Your characterization of ZFS has simply a LVM combined with a file system and some glue is sadly mistaken. You might want to visit the ZFS community at OpenSolaris
http://opensolaris.org/os/community/zfs/
to learn why its completely different than a simple combination of those two components.
In particular, look at the Source Tour.
