What about conflicts, when two applications register with the same priority? And then one of the them exits, dies, fails, and re-registers itself. Does it get the same slot back? Does it goto the end of the line? If it's an HSM handling (or other content manipulation tool) what happens? These are the questions which need to be answered, and the ABI updated to reflect these questions. Even if it's just "We don't care..." it needs to be spelled out. John
