Pushdown systems synchronizing by unbounded, reliable fifo queues seem a quite natural model for distributed systems that communicate via TCP or MPI. Recent publications focus on the influence of constraining the network architecture on basic decidability questions, but do not allow to derive positive results beyond control-state reachability when assuming syntactic and semantic restrictions that are still "applicable" in practice. We present first ideas on leaving behind interleaving semantics in order to verify MSO properties based on a graph grammar based representation of a system's partial-order behaviour.
