I think it would be more interesting to take ports found on many computers that aren't being used and turn them into GPIO.
There are Ethernet to Serial adapters [1] [2], I wonder if it could go further. There is also dvi, hdmi, displayport with lots of wires and a chip behind them. Displayport even has " A bi-directional, half-duplex auxiliary channel" [3] , though I'd want to look at the spec to see how that could be used, or if it could be contorted to a GPIO purpose.
