Narrative:

Pushed back from the gate in bright sunshine. Given runway 17R for takeoff. East half of airport shrouded in fog. West side in the clear. Fog was drifting in from the east then being burned off by the heat of the airport surface. Asked ground control RVR for 17R. Reply was 800-1000-1400. Asked RVR for 18L. Told better than 6;000. Asked why we were taking off from a runway with cat III weather when there was a VFR runway available. Told because procedures for our departure direction dictated 17R. Since we could legally use 17R we did; RVR had also come up enough so that the first officer could legally make takeoff. Climbing out northward; we looked back and could still see 18L and right in the clear while 17L and right were buried under fog and were left shaking out heads at yet another instance of ATC not letting common sense get in the way of routine procedures.

Title: Because of routine procedural considerations and to the consternation of the flight crew; MCO ATC required a B757-200 to take off on a Runway shrouded in CAT III level fog instead of utilizing available same direction runways in the clear.
