I have several PC's around the house capable of playing AH. It would be nice to be able to use them to join myself and have multiple monitor views. I think that it could be accomplished using a 'Join-From-LAN' feature that only allows the views to be set (with the joined pc's communicating only with the PC that is connected to HTC.). The joined computers should only have the ability to view from the cockpit, not move or use any gun positions, or communicate over text/vox. Basically they would only be a way of adding multiple monitor support to the game.
