[mosh-users] How can I mosh over multiple hops (for example, via tunnel or ProxyCommand)?

I'm in the same case. I think there are two solutions.

1. Use a UDP packet repeater.

http://serverfault.com/questions/390916/mosh-tunnel-via-proxy
suggests stone. I'm wondering whether socat or netcat could be
used as well. But such a tool needs to be installed on the
gateway. So, I'm suggesting a second solution:

2. Use mosh to connect to a server X with a permanent connection,
then ssh on the other side. This is what I currently do, and even
something like:

        mosh                      SSH[*]
Mobile -----> screen on server X ----> Host A
                                 ----> Host B
                                 ----> Host C

[*] possibly with ProxyCommand.

Now I'm wondering whether mosh could be used in some reverse mode,
e.g. because one side is a smartphone (which can move and can be
behind a firewall), the other side is a laptop (which can also move
and can be behind a firewall), with a possible use of a server with
a permanent connection in the middle.
