A regular 100MB Ethernet connection only uses 4 of the actual wire in an RJ45.
I really don't care about the speed that would be associated with (Cat3?) untwisted wire. Would i have to buy Rj45 modules to put on the wire?

CAT3 cable is twisted, just not as much, but it's only rated for 10 MB, not 100 MB. It may work for short distances, like for a temporary patch cable replacement, but I wouldn't use it for anything permanent. 6 months from now a simple change in the environment could give you all kinds of trouble, and you might not relate it to using CAT3 instead of CAT5/CAT5E cable.
Not worth the difference in cost.

The flat untwisted cable often used for connection a phone to the wall would not be reliable at all.

You'd have to use the RJ45 connectors. The 4P4C will plug into an RJ-45, but connects to pins 3,4,5,6. Any Ethernet device uses pins 1,2,3, and 6, so that won't work.

Of course I know all the answers; I just don't always match the answers to the right questions.
