Oh, I see, thx. I think it's better to create one JS-object where to store these values, since accessing global variables is quite slow in JS. It's not mandatory at all, just to your decision, but you may pass it to `start` function in a way like: 

```html
<body onload="start({ playerDomain: $playerDomain$, ... })">...
```

or by assigning:

```javascript
// ...
<script type="text/javascript" src="$publishScript$"></script>
<script type="text/javascript"> 
    document.body.addListener('load', // actually, it should be DOMReady, I should fix it in `go` page also
       function() { 
            start({
                playerDomain: $playerDomain$,
                ....
            }); 
        }
    );
</script>
```

and to add some `opts` parameter to `start` function:

```javascript
var start = (function () {
     // . . .
     return function(opts) {
     }
})();
```

this way we'll only have `start` function is in globals.
