"The quick slick hack, as you've probably already guessed, was
connecting the wireless laptop to the PC with an Ethernet patch
cable, and then creating an Ethernet bridge between the wired and
wireless NICs on the laptop. It worked like a charm, and I didn't
even have to hassle with finding a crossover cable because you
don't need one with Gigabit Ethernet interfaces. (GigE for cheap- I
love modern times.)"
