Which JavaScript libraries will handle popout windows (i.e. like Meebo or Gmail chat windows)?
<p>I could write this, but before I do, I wanted to check to see if there are existing solutions out there since it seems a lot of websites already do this, so I was wondering if there was a quick way to do this.</p>

<p>Also, I am talking about "popout" windows, not "popup" windows.  All JavaScript libraries support "popup" windows, but I want ones where they originally open as "popup" windows in the same browser window, but there is also a link to open them up in a brand new browser window.</p>
