Another strong negative with SSHFS (at least the last time I tried it)
is that it's very sensitive to network outages.  NFS (in my
experience) can pick up after any length of network outage without
blinking, but SSHFS died permanently and inelegantly after its
built-in inactivity time-out (set in the SSH configs, usually ~15
minutes?), and the cause isn't immediately obvious.  Perhaps that
could be fixed by making the time-out infinite ...

All of that sounds marvelous.  Is it actually happening?  According to
this - - 2.6.x kernels support nfsv4.  But
is  encryption implemented?  Is it automatic if both client and server
support v4?  Has anyone used this and/or seen it in action?  I used to
use NFS a lot, but its relative insecurity and clear-text transmission
put me off.  I have less use for it now, but I'm still very
interested.  Thanks.
