But you still have to have two people accessing the machine at one time, right?

Now that I think about it, I was at a company once that had a device that was supposed to allow multiple people to access the computer at the same time (it was supposed to create a second console, or some such). We could never get it to work, but if I can remember what it was, I'll let you know.

BTW, a key in the parallel port == ``dongle''.
