Shouldn't we be able to get by with just one of these, since the instance name should be unique within the particular service? Yeah, I was wondering about that too. Surely the action name is all that's needed and that only needs to be unique on a per service basis, right?

Personally I think the nickname will drive people bats because they'll need to perform some form of translation/mapping. I'd think that the name people see should be all they need to have to take them directly to the service/action definition in question i.e. no translation required.
