hmm...
I wish you guys would actually read the documentation we've written...
Media directors run the LinuxMCE software.
If the device can't be booted diskless over the network using PXE, it can't be used as a media director, and thus doesn't run the orbiter software, or the media players, etc.
We DO have a upnp server, so that UPnP devices can play media on the core. However, they do not have control of the home automation functions.
I will not repeat this again,
