If it proves too cumbersome to enable direct host to host communications via usb then we will simply ship a 15" flat screen, kb and mouse with the unit and have them returned afterwards.
or, use commercial servers with integrated TCP kvm's such as HP's iLO, Dell's DRAC, Sun's ILOM, etc. These provide virtual consoles and CD/DVD's over IP where the client side just needs a java enabled web browser. they generally have their own ethernet ports for this, and you assign them a dedicated IP address. most require SSL (https:) to connect, so are quite secure.
