Service B on node 2 depends on Service A on node 1.

Per Scott, "Dependencies on components that are marked as @Clustered needs a cluster aware dependency implementation. Custom dependencies are supported by the mc, but the component deployers generating the component metadata have to generate the correct dependency implementation."

This also ties in with the coordinated deployment issue in JBAS-5553, as we wouldn't want Service B deployment to fail on node 2 just because it happened to deploy before Service A on node 1.
