+@section Metadisplay Server
+
+A metadisplay server is a server that is connected
+to one or more display server's simultaneously.
+Additionally, it is acting as a display server on
+its own. Any server, or even client, running in
+this display will effectively be running in all
+of the displays connected to the metadisplay.
+
+The idea of the the metadisplay server came from
+the idea of letting the user have the clipboard
+shared across any number of @emph{selected}
+display server. Rather than having a clipboard
+server written specifically for this, it was
+seen as more appropriate to have a server than
+could let any server run inside any number of
+display server. Not only will this let the user
+run any server this way. It also makes it possible
+to run them across any number of computers.
+
+If a hosting server, like @command{mds-host}, runs
+inside a metadisplay, any number of computers can
+connect to the metadisplay using a server like
+@command{mds-remote}. This creates a metadisplay
+with multiple display from multiple computers.
+If a clipboard server runs in this metadisplay,
+all of these display on all of these computers
+will share clipboard server.
+
+Whilst not removing or degrading any functionality.
+A negative property of this setup it that it is
+centralised rather than distributed. If the computer
+hosting the metadisplay crashes, the other computers
+will no longer share this metadisplay, and lose the
+connection to any server running in it.
+
+In addition to a the clipboard server, there is a
+host of other servers that makes sense to run in
+multiple displays or across multiple computer:
+drag-and-drop servers, human input device servers,
+output servers, and even windowing servers.
