Is there a way to get a list of all the open browser windows if they are from the same domain as the window that is trying to get the list?

In general, no.
Unless there is a "connection" between the windows (e.g., one window opened all the other using window.open), browser windows can't interact because of security reasons.
Edit:
If you assign a name to your window, you can regain control over it after refreshing the parent page.
windowVar = window.open('somePage.html', 'windowName'); opens a child window with name windowName.
After refreshing the parent page, windowVar = window.open('', 'windowName'); re-associates the variable windowVar with the window of name windowName.
Now, windowVar.location.href= 'logout.html'; lets you log out your user.
Edit:
Assuming you use PHP, you could do something like this:
Create logged.php with a function logged_in that verifies if the session ID is still valid.
<?php
if (isset($_GET['sid']))
if (logged_in($_GET['sid']))
echo "in";
else
echo "out";
?>
Include check() function in your pages.
function check()
{
var url = "http://redtwitz.com/test/logged.php?sid=" + sessionId;
var request;
try
{
request = new XMLHttpRequest();
}
catch(error1)
{
try
{
request = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(error2)
{
request = new ActiveXObject("Microsoft.XMLHTTP");
}
}
request.open("GET", url, false);
request.setRequestHeader("User-Agent",navigator.userAgent);
request.send(null);
if(request.status==200)
if(request.responseText == "out")
window.location.href = "logout.html";
}
Call check function every 5 seconds.
<body onload="setInterval(check, 5000);">
