Is acceleration relative? (In the same way that velocity is)

Well then I think the question is in same category as: "Can a chicken lay an egg while traveling on top of a photon".

Haven't I seen the words "inertial frame" in some of your posts. We must be careful or we will be using things such as rigid rods and point particles next.

Wouldn't a non-local quantity imply a scalar?

But isn't a clock defined by a a definite integral, which is a nonlocal quantity?

That is not what is usually meant by "local", particularly in this context. Usually what is meant is that it is some experiment that you could perform in a small isolated room without reference to anything external to the room. Small means small enough in space and time to ignore any curvature.
