Or just run 1, why do you need more?
My own reasoning, in similar circumstances was... I needed (say) two devices at the remote location. I could have laid a single cable with a switch at the far end, but cable is cheaper than switches... so I ran two cables.
Trouble is, you will always need more than you think, even if you allow for the fact that you will always need more than you think. So chances are, one day, you'll end up with another switch regardless... in which case, a single cat 5 might have sufficed.
