Fuse on FreeBSD doesn't support VFS operations that are required
by the NFS server. VFS_FHTOVP(), VFS_VPTOFH() and the stuff that
allows a mount point to be exported are some, there are probably
others.

How much work would it be to add this capability. At this time
I have no idea since I am not conversant with Fuse.
