[SalesForce] How to open a Visualforce Page in a tab into the Service Console lightning

Here is a small experiment as a proof of concept to emit events from lightning component and handle in VF

<aura:component>
 <div> Hello World !!!! </div>
  <aura:registerEvent name="myevent" type="c:myEvent" />
  <ui:button label="fireEvent" press="{!c.fireevent}" />
</aura:component>

The JS controller file

({
 fireevent: function(component, event, helper) {
    var myEvent = $A.get("e.c:myEvent");
    myEvent.setParams({"data":"Test"});
    myEvent.fire();
  }
})

The Event file

<aura:event type="APPLICATION">
 <aura:attribute type="string" name="data" />
</aura:event>

The application file

<aura:application access="GLOBAL" extends="ltng:outApp">
  <aura:dependency resource="c:myComponent" />
</aura:application>

The visualforce where event is handled

<apex:page showHeader="false" sidebar="false">
<apex:includeLightning />
<div id="lightning"> Hello world VF ..!!! </div>
<script>

    $Lightning.use("c:myEventApp", function() {
        $Lightning.createComponent("c:myComponent", {}, "lightning", function(){
            $A.eventService.addHandler({ "event": "c:myEvent", "handler" : visualForceFunction});

        });
    }); 

</script>

<script>

var visualForceFunction = function(event){
        var myEventData = event.getParam("data");
        console.log(myEventData);
    };

</script>

DISCLAMIER : I have not tried inside service console but this should help you get started .For ISV apps since this is not documented anywhere ,consult SFDC security review team or salesforce lightning component product team to see if this is right way of doing this .

You can use sforce.one.navigateToSObject('{!asset.Id}') which will open a record in new lightning console tab.
