Yes you can use the direct javascript api jsf.ajax.request instead of
ajax then you can use full identifiers.
<h:commandButton value="Login" id="login-button">
> <f:ajax execute="user-name password" render="out" />
> </h:commandButton>
would become
<h:commandButton value="Login" id="login-button"
onclick="jsf.ajax.request(this,event,{execute:'@this',
render:'form1:out'});return false;">
</h:commandButton>
As you can see the render now is mapped to the full client identifier
form1:out
That way you can make render submits outside of your form.
However, I have to recommend to update to the latest trunk or the soon
hopefully to be released myfaces 2.0.1 if you want to do cross form
submits or submits with renders outside of your current form.
I did a load of improvement especially in this area for the scripts so
that cases like updating a cross form element does not cause problems
anymore with other forms where the element might be embedded or which
has another form embedded :-)
Here is a code snippet from one of my testing cases dealing exactly with
what you want to achieve:
http://www.pastebin.org/358867
Have in mind that all this works in the current trunk (and soon in
2.0.1), but the 2.0.0 codebase and also Mojarra has some limitations.
(mostly if you update elements which embed forms, or in case of MyFaces
2.0.0 also if you update elements within another form than the issuing one)

Is there a way to make the following code work, apart from placing the

At the moment the following exception is thrown by JSF when rendering
the page:
|<f:ajax> contains an unknown id'out' - cannot locate it in the context of
the component login-button|
