Too bad mosh needs an udp port to run its own server.

One of the greatness of ssh is its lean network requirements (it can even be considered https if seen from intermediate proxies, hence whitelisted) and this extra udp port is quite a burden in some environments.

I still agree that mosh is a fine tool for mobile users. I'm just a tad worried about its security layer implementation being less audites than openssh for instance (as mosh isn't as widely used)...

Well, Mosh still uses OpenSSH for the initial authentication, and during the rest of the connection, all the security is handled by a single layer (AES-OCB, using the reference implementation), which is not specific to Mosh.

That said, it has never been audited.
