If multiple empegs are on the network it (should) provide a control menu for each.
Well, I have multiple empegs on the network right now, and it works, but with one problem...

  PID COMMAND      %CPU   TIME   #TH #PRTS #MREGS RPRVT  RSHRD  RSIZE  VSIZE
  580 EmpMenuX    38.2%  1:03.37  13   293   223  13.0M  15.9M  19.5M   293M

If I pull the power on one, the app removes the control for that empeg, and goes back to being unnoticible in CPU usage. This is with the display options like stocks and weather turned off on all units.
