Ok - this is a slightly different situation as these devices are pulling media from MC to playback locally, MC is not "instructing" the device to play and MC can't see those devices as renderers or destinations, but I see your point in that "Playing Now" implies that you can see, literally, everything that is playing now and not just a list of devices that MC can control. I think the idea of Playing Now would have been origianlly as a central control area for all controllable devices (rather than an area to spy on devices - why else would you want to see what is playing if you can't control it!), whereas with Gizmo and WebGizmo only those devices can control the media beaing streamed. Developers would need to make an enhancement here I think!
