If you're going to run the file system in user space, there's no reason not to just use normal ZFS. The problem with ZFS licensing is only in combining CDDL+GPL in one unit. If you're working across the kernel/userspace boundary, there's already no problem. ZoL even already ships a fuse version that works fine.

This is not true. A FUSE implementation is wanted though: https://github.com/zfsonlinux/zfs/issues/8

Oops; I didn't realize the existing fuse version wasn't built from ZoL. Thanks for pointing that out.
