local+ssh sounds more like your second scheme

Attempting to generalize/abstract a naming convention:

    ssh {host} socat - UNIX-CONNECT:{path}

I'm not clear what's a protocol and what's a transport here; it seems to
me the actual data exchange protocol is always mtn (that defines how to
exchange certs, keys, revisions, and possibly authentication), and both
ssh and unix domain sockets are transports.

This connects to a running remote multi-session server; other choices
start a single session server.

    ssh {host} socat - TCP-CONNECT:localhost:4691

here we have ssh and tcp sockets as transport, and it connects to a
running remote multi-session server

other choices:

    mtn:

tcp sockets as transport, connects to a running remote multi-session server

perhaps this should just be named tcp? 

    file:

unix domain sockets as transport, start a single-session local server.

    ssh:

ssh as transport, start a single-session remote server

That's good.

Now is the time to rename it, if we are going to. But so far, I don't
see a clear naming convention. 


This discussion suggests a way to make file: work on Windows native; use
TCP sockets to connect between the client and server instances of mtn.
