YES !! My Idea EXACTLY.
You would have to specify IP's of other units for your unit to look for.
then multiple networked units could "recognize" eachother,
and then in "Playlists" you would get "Local Lists" and "Other Empegs"
Select "Other Empegs" and you get a horizontal list of other empegs on the network,
selet an Empeg on the network, and you are dropped into the playlist tree on that empeg unit.
Bring on the diskless Empeg.
