Consider yourself corrected :-) Two pairs are used for 100BaseT & 10BaseT. So
it is possible to run two connections over one run of Cat-5 cable, and as
somebody else pointed out, you can even buy little gadgets to do that and save
you rewiring sockets at each end.

I would suspect that maybe over longer cable runs this mightn't be as reliable
as a very reliable thing because of crosstalk, but that's really only
guessswork/gut feeling.
