OK, I just wanted to make certain that we didn't make things more complicated than required. And since the requirements were to prevent editing, I didn't see the point of mentioning Readers fields.
I live by the Extreme Programming rule: "Do the simplest thing that could possibly work" and "Always implement things when you actually need them, never when you just foresee that you need them."
