Rewriting systems working on words with a center marker are considered. The derivation is done by erasing a prefix or a suffix and then adding a prefix or a suffix. This can be naturally viewed as two stacks communicating with each other according to a fixed protocol. The paper systematically considers different cases of these systems and determines their expressiveness. Several cases are identified where very limited communication surprisingly yields universal computation power. © Springer-Verlag Berlin Heidelberg 2006.
