In php I set a persistent cookie to do something similar, if it can be accessed from separate browsing sessions it can be accessed cross-domain i'd imagine.

I have "borrowed" this javascript from @pete because I'm not a JS expert, and barely even a novice, but I think something along these lines could work, set a cookie to expire after a year or other time period, as opposed to when browser session closes or the page has been left.

You'll need to do some messing about with it but hey, that's the fun part!

// Build the expiration date string:
var expiration_date = new Date();
var cookie_string = '';
expiration_date.setFullYear(expiration_date.getFullYear() + 1);
// Build the set-cookie string:
cookie_string = "test_cookies=true; path=/; expires=" + 
expiration_date.toUTCString();
// Create or update the cookie: 
document.cookie = cookie_string;
