Could have some issues with crosstalk. I believe that the reason the IEEE
went with 4 pair cat 5 is for the insulating capabilities of it as opposed
to 2 pair cat 5.

It certainly -can- be done, but it isn't recommended. I've had cases where I
needed to temporarily have two network jacks over one physical cat5 cable.
For this, I just split off the other pairs and crimped another RJ45
connector onto them. I was even able to run fast ethernet over both of the
runs, and it worked reliably for the time that it was needed - well over a
month. I've even had instances when I needed to temporarily run a single
fast ethernet connection over cat3 "phone" cable. Ethernet isn't as picky
about signaling as the IEEE allows it to be, but I wouldn't make a habit of
stretching its limits.
