In these scenarios, I have done a poor mans VPN with SSH instead of
fetching.  Using RSA keys, build a port forward from the BB/hobbit client
local 1984 to the BB/hobbit server.  You then configure the BB/hobbit
client to use localhost as its BB/hobbit server for communications.

This is "trusted Network' to 'DMZ" security friendly . . .

I then run a monitor on the BB/hobbit server, that attempts to detect the
VPN, and create if it doesn't exist.  The VPN is 'activated' by an "rvs"
tag in the bb-hosts file.  I have had issues with the monitor attempting
to build multiple tunnels, but haven't pinned it down.

This all presumes the bb/hobbit user on the bb/hobbit server can signing
via ssh to the bb/hobbit client without passwords (using keys).

Personally, I prefer unencrypted user private keys over HostBased.
