Actually, the protocol that does this is not only useable with Gnu Emacs.
It is a quite generic protocol for remote screen updates (ie, the terminal
servers handles cursor movement, function key processing and most screen
updates, and only notifies the host application in large chunks about what's
happening. Currently, however, Gnu Emacs (18.44 or some similar older version)
is the only application that the LEAP (Local Editing Accelerator Protocol)
protocol has been implemented in.
