Common law and civil law legal systems are fundamentally different, and they differ meaningfully in how NDAs get written on them. I doubt a single set of terms could cover both kinds of jurisdictions without more or less sticking two NDAs together with an IF THEN ElSE between them.

I am just an American lawyer. Working with colleagues from the UK, Australia, New Zealand, and Canada on Waypoint and Guestbook, I was surprised how well one set of terms could serve clients under all those systems.
