It would be simple enough to program a computer to comunicate with a bunch of another computers through the keyboard (usb) port, using keyboard signals, so it would be impossible to determine if you were multiboxing or not. Just throw in some random delays and some random spell choices and problem solved ...... You could only have one client per computer though but thats also no problem if you buy a bunch of cheapo computers. Of course you wouldnt be able to brag about it lol .....
