Only theoretically. To the extent that the spec mandates things just not
possible on top of POSIX, the two cases become different. That said, I've
already told Sean that it's not really useful to harp on the specifics until we
see the real barriers POSIX puts up as D-VFS is implemented.
hat makes them any more unusual to handle in the kernel than, say, NTFS.

Or CIFS ones on SSH ones, or any of a number of others already supported by
various kernels.
