mosh is very useful for intermittent connectivity. Anytime I had to rely on spotty 2G/3G/wifi, the usual workflow "work locally ; git push" failed, as it's TLS/TCP and not resumable. Had to autossh+rsync the diffs out onto a stable host in the cloud, and then essentially worked from there.

Also, I have a mosh client on my smartphone; setting up the dev environment there would be a bear. Essentially the mainframe model ;)
