+Applications that want to embed another other
+application within it, should create a socket
+and start the other application with the
+environment variable @env{MDS_EMBED} set to
+the windows ID of the socket that the application
+should be embedded in.
+
+All @command{mds} applications must be aware
+of the environment variable @env{MDS_EMBED}.
+The application may choose not to embed itself
+in the announced socket, however it should have
+good reason for not doing this.
+
+All @command{mds} application must unset the
+environment variable @env{MDS_EMBED} before
+it starts any other program.
