[ If one of the two computers has a free ethernet port, you can of course also such a dongle on the other computer. ] BTW, those ethernet dongles can be found pretty cheaply (like $10 or less) and they can be handy in many cases to add an ethernet port (or several ports, even). IOW, it's a good tool to have in your box. Stefan
