I used a SRAM X series derailleur on my custom P20... have never had a problem with things striking the derailleur and many a Bike Friday is also built like this. The Sram does sit higher than a traditional long cage rear d.
One should always strive to stay out of potholes and avoid rocks big enough to take out your rear derailleur.
