Slimserver support is built-in to LMCE. This makes installation of squeezeboxes very easy, and they work well for playing music. Support for messaging could be added, but with the relatively small display area, I wonder if the menuing would be too clunky to be useful. I thought I read about a plugin to Sliserver that allowed you to stream to a Roku. If so, that might be workable in LMCE, but personally I would advise you to stick with the squeezebox.
