That's exactly a common usage pattern for me.  I frequently connect to
customer machines that some network VPN magic makes accessible as if
they were in our local network, so hostA and hostB are 192.168.233.1 and
192.168.233.2 from my POV although in that customer's network their IPs
are different.
