Angular2 using @Inputs with <router-outlet>s

Question

I have a sub-navigation in my page that displays some subviews below a common main view. I would like to pass an object to the subviews through the <router-outlet> so that I can retrieve the data once in the main component and just share it with my sub components.

Note: If I include the directive <one></one> in the main.html it works but this isn't my desired behavior.

Main View:

<h1>Details</h1>   
<a [router-link]="['./sub1']">One</a> | 
<a [router-link]="['./sub2']">Two</a> | 
<a [router-link]="['./sub3']">Three</a>   
<hr/>  
<router-outlet [data]="maindata"></router-outlet>

Sub View 1:

<h2>{{ data.name }}</h2>
...

Main View:

@Component({
    selector: 'main-detail',
    directives: [ROUTER_DIRECTIVES],
    templateUrl: './main.html'
})
@RouteConfig([
    { path: '/', redirectTo: '/one' },
    { path: '/one', as: 'One', component: OneComponent },
    { path: '/two', as: 'Two', component: TwoComponent },
    { path: '/three', as: 'Three', component: ThreeComponent }
])
export class MainComponent {
    maindata: Object = {name:'jim'};
}

Sub View 1:

@Component({
    selector: 'one',
    directives: [CORE_DIRECTIVES],
    inputs: ['data'],
    templateUrl: './one.html'
})
export class OneComponent {
    @Input() data;
}

If it's simple data you can pass them through RouteParams

<a [router-link]="['./sub3'],{name:'jim'}">Three</a>

then in your sub view

@Component({
    selector: 'one',
    directives: [CORE_DIRECTIVES],
    templateUrl: './one.html'
})
export class OneComponent {
    data: any;
  constructor(params: RouteParams){
    this.data = params.get('data');
  }
}

You can also setup the route to always pass params from the component by moving the RouterConfig INSIDE the component (Note, this is not how it's normally done):

export class AppCmp {
  history: string[] = [];
  constructor(public list: PersonalizationList,
              private router_: Router) {
    list.get('histoy', (response) => {
      this.history = response;
    });
    router_.config([
      { path: '/', component: HomeCmp, as: 'Home', data: this.history },
      { path: '/about', component: AboutCmp, as: 'About' }
    ]);
  }
}

If you are going to do something more complex I suggest using a service to communicate between routes/components. It's actually the way I prefer to do it.

Sample Service:

import {Injectable} from 'angular2/angular2';

@Injectable()
export class CarsService {
  list1: array<any> = ['a','b','c','d'];
  list2: array<any>;

  constructor() {
    this.list2 = [1,2,3,9,11];
  }
}

How you Inject a service:

export class Cars {
  constructor(cars:CarsService) {
    this.cmpList1 = cars.list1;
    this.cmpList2 = cars.list2;
  }
}

This way you can use the service to communicate regardless of parent/child or other weird restrictions.
