app (or window.app) is and should be the only global.
The only place it's ok to modify app.* properties is in index.js.
The only places it's ok to modify app.state.* is in actions (in src/js/actions/*.js) or in index.js.
If these restrictions cause problems or gnarly code, bring it up and we can discuss.
The app.* globals:
- app.remote: The rpc-multistream connection
- app.state: The ashnazg application state
- app.actions: Actions (functions) that modify application state
