Do you know of a precedent for this? One thing that NVI has going for it is that it's quite established - it seems to be solidly planted in programmers' lore. I was surprised to find 2.8M Google matches for the exact string "Non-Virtual Interface".
Looks like it's considered a design pattern, and design patterns are popular. I think the idea itself is relatively obvious and useful, so it's likely to encounter it often. (I didn't even know it's called "NVI".)
By the way, Aspect Oriented Programming also seems to reinvent this idea with pre/post code for methods (see Yigal's posting).
