08 NEC:

"800.110 Raceways for Communications Wires and Cables.
Where communications wires and cables are installed in a raceway, the raceway shall be either of a type permitted in Chapter 3 and installed in accordance with Chapter 3 or listed plenum communications raceway, listed riser communications raceway, or listed general-purpose communications raceway installed in accordance with 800.154 and installed in accordance with 362.24 through 362.56, where the requirements applicable to electrical nonmetallic tubing apply. The raceway fill tables of Chapter 3 and Chapter 9 shall not apply."

Plumbing PVC is neither listed in Chapter 3 or listed as communications raceway. 352.2 and 352.6 would seem to exclude using plumbing PVC over grey RPVC.

The question is more important than the answer.
