I did a small test: dual boxing on the same machine (the mac) thing went quite well even if i have to admit with some problems (after 15 secs I had 2 shamans going in totally opposite directions and i swear i was gettin more than nervous). The loot problem is crap, questing when there are items to loot will be a pain this way. But it was working in the end. Next step will be using 2 different machines. Ok i will buy the copies of the game I need for the combo later today (the disease is spreading). Thx for the kind support. I will keep u informed about the progress (if not too busy playing ).
