THANK YOU!
I've been convinced of this for years, and all the explanations have always left a bad taste in my mouth - they all rely on "instant" transmission, which, as a computer scientist, makes me instantly suspicious.
Sadly, I don't have the physics background to prove it, but Lorentz transformations have always seemed the key to me; logically, there must be a frame of reference that provides a completely linear perspective, so any travel can be translated into this frame.
If there is such a monotonic frame, then as long as you don't violate causality in this frame, you can't be violating causality in any other frame, it just appears that you are, like an optical illusion.
What you describe as the co-moving frame seems to match this idea...
