> One NDA I was required to sign explicitly stated that every idea or functionality I developed on other projects for up to twelve months after delivery of their project was subject to review by the issuer of the NDA

Saying 'required' makes it sound like you didn't have a choice -- out of curiosity, did they have other leverage over you above getting your help on their project, and did you attempt to negotiate on this clause?

I don't doubt that non-compete clauses happen in NDAs; other people in this thread to mention seeing them. But I think they're not that common either. I've seen my share of NDAs and never seen a non-compete clause. I do get non-compete clauses in employment contracts that also include NDAs as well as invention assignments and more, but I haven't personally seen a non-compete clause in a pure non-disclosure contract, that seems abnormal. But I agree completely that one should always read their contracts carefully before signing.
