Also I can SSH/VNC/Xwindow/whatever into a server machine with performance stats far beyond any currently imaginable laptop. Its like owning a laptop from 2023 today in 2013.
Easier and more reliable to have everything working locally (With local dev environments using vagrant/virtualbox) and use the internet connection for syncing git changes or doing research.
How Mosh works Remote-shell protocols traditionally work by conveying a byte-stream from the server to the client, to be interpreted by the client's terminal. (This includes TELNET, RLOGIN, and SSH.) Mosh works differently and at a different layer. With Mosh, the server and client both maintain a snapshot of the current screen state. The problem becomes one of state-synchronization: getting the client to the most recent server-side screen as efficiently as possible.
This is accomplished using a new protocol called the State Synchronization Protocol, for which Mosh is the first application. SSP runs over UDP, synchronizing the state of any object from one host to another. Datagrams are encrypted and authenticated using AES-128 in OCB mode. While SSP takes care of the networking protocol, it is the implementation of the object being synchronized that defines the ultimate semantics of the protocol.
