[mosh-devel] Termius + Mosh

[Keith Winstein]

Hello Roman,

Okay, but if we can't see your code, we don't have a good way to start to
know if your implementation is "fully compatible" with Mosh (it's not like
we have a compatibility test suite for new binary implementations). If you
didn't implement it with clean-room approach and were referencing the Mosh
code as you wrote your own implementation, we can't tell you if your
program is a derivative of Mosh or not. I do appreciate your kind words
about Mosh.

Sincerely,
Keith
