I forgot:  And doesn't NFS require stable inode numbers and other
"invariables" like that for it to work?  FUSE doesn't and those
requirements are a real PITA in a lot of cases where there simply are no
inodes and the numbers are synthetic and change on each remount or even
on each access after the dentry has expired...

And I always thought that doing FS in userspace via NFS is considered an
ugly hack.  I didn't have the impression that that had changed recently.
