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."

Because a FUSE driver wouldn't have to link to the GPLed kernel and would consequently not present a license conflict. Also, there was already work in progress on a FUSE ZFS impl for last year's GSoC, though I have no idea how far that progressed in the end.
Update: Err, missed the actual point. The FUSE driver could, due to the lack of license issues, use the actual ZFS code, which would prevent the patent issue from cropping up.
