[mosh-devel] High latency satellite connections

Hello Numair,

We think it's a great idea! In theory, it should work fine and you
should not have to make any changes to the source.

The SSP timing parameters are in src/network/transportsender.h.
Glancing at them, I don't think any are clearly inappropriate for a
satellite link (famous last words...). We might learn differently
after actually trying it though. If anything we may want to make the
local echo MORE aggressive and allow it to go brashly over a tentative
boundary even though it's more likely to show a mistaken production
for a little bit.

Please let us know if you try it and what the results are!

Best regards,
Keith
