Just ssh your Media Director and follow the instructions of my first post except for the deviceTemplate creation step (php lcdprocclient-devicetemplate) that must be done once on the core.
To configure your lcd see http://lcdproc.sourceforge.net/docs/stable-0-5-x-user.html and modify the /etc/LCDd.conf file on your MD.
Make sure the 'ServerScreen' option is set to 'no' if you don't want to see the server screen displayed between LMCE messages.
You will have to do the all thing each time you rebuild your MD.
Remember it's not officially released and I have compiled and tested the device with a clean 0710 LMCE 32bit install, use at your own risk...
