Mosh to the Moon (really big delays)

Hi,

I'd like to use mosh to comunicate with a spacecraft on the moon. The problem is that round trip time earth->moon->earth is between 3 and 4 seconds.

What I already did is changing MAX_RTO in network.h from 1000 ms to 10000 ms. This allowed me to establish a stable connection between mosh-server and mosh-client.
But there are two remaining problems.

1. As we do not have TCP or SSH available we have to use another way of starting the mosh-server, getting the cryto-key down to earth and connect a mosh-client to it. How can I increase the initial timeout period before the mosh-server terminates itself when no mosh-client is connected?
2. When I start to type in my local mosh-client there is quite a delay before I see what I typed. When I keep on typing eventually the underlined characters appear indicating not confirmed letters by the server. Also deleting characters in my local console is quite laggy. It there a way to make mosh more responsive even with round trip times of >3s?

Cheers

Start with network.h and the mosh-server and mosh-client startup paths described in the issue. Investigate the initial no-client timeout and delayed input behavior under a 3–4 second round trip; done means both connection setup and interactive typing remain usable without TCP or SSH.
