You can also create variations of pieces to give you up to 32 names (wPawn1, wPawn2, bPawn1, etc) or board squares for up to 64 names (A1, A2, etc).
Another variation works on the premise that when starting a new network, all your new machines would have a name in chess notation (Nc6 or b7toc6 or Knightc6 or similar). When the 'game' is over, start a new one from a different starting position...you should never run out of possible names. Also, you can store all your games in a PGN text file to see the history of your devices.
