I think we’re thinking similar. Although, in the future state, I’d expect it to be something like

```auto
experiment:
  ...
  runtime:
    ...
    monty:
      ...
      environment:
        _target_: ${monty.class:tbp.monty.environments.HabitatEnvironment}
        ...
    environment:
      _target_: ${monty.class:tbp.monty.simulators.HabitatSimulator}
      ...

```

`Monty` would only receive the `monty: ...` portion of configuration to instantiate. Similarly, `Environment` would only receive the `environment: ...` (`monty` sibling one) portion of configuration to instantiate.

In my translation above, `habitat_ipc.server` part of the tree ends up being the simulator (there’s a separate discussion that on the environment side, environment and simulator are pretty much the same). The `habitat_ipc.client` part of the tree ends up being the `HabitatEnvironment` which is basically the interface to the enviroment (local or remote).

I think the general shape is like the above, although the details will probably look different once we get to that point.

Yes, this aligns with our intentions as well. Namespace things correctly before extracting them. That’s part of our plan for extracting experimental framing, for example.
