A student and I flew to Cedar City and were on a practice ILS approach for Runway 20. There was a small airliner a few miles ahead of us and a Bonanza behind us. We were all using Runway 20. We were in radio contact with both of these planes while on approach. As we were descending on the ILS we made radio calls ten; seven and three miles out. The event occurred after we touched down on Runway 20. As we were rolling down the runway; another aircraft landed or was taxiing on Runway 08 and came across our Runway 20. I was able to stop our aircraft once I noticed the other aircraft coming onto Runway 20. The other aircraft also stopped once it saw us. We were both at the intersection of Runways 20-02 and 08-26 and approximately forty feet apart. I waved the other aircraft through the intersection and then followed it to the ramp. Once there I spoke with the pilot and asked if he heard us on final. He said that he heard our 10 mile call but that was all. I asked which frequency he was on; he replied the CTAF 123.0; which we were using as well. I inquired if he and his passengers were okay; and expressed my relief that there was no accident. We then left and flew back to base.
A DA-40 pilot landed on Runway 20 at CDC and found another aircraft rolling out on Runway 08; entering the intersection ahead.  The other aircraft was easily avoided and the event was discussed upon arrival at the ramp.
