At any rate... if I were in your shoes and really restricted to the options you propose, I would go with CIFS mounts through IPSEC tunnels.

Wouldn't IPSEC add more  overhead than an SSH tunnel?


I would *certainly* not use ssh-tunnels, on a line that is not 100% error free or with high latency.
In general tcp-in-tcp tunneling is BAD. One likely gets the infamous snowbal-effect.

As ipsec is lower in the protocol-stack (then openvpn) it has probably the lowest overhead.
ssh-tunnels are the worst (just nice for a quick tunnel in SOHO-environments)
