https://github.com/panique/php-long-pollingJust checked it, it works with server.war2.ru.
And it's also pretty easy and understandable for me. Could be rewritten for any our tasks easily.
Long-polling is the way to handle the server-side activity on your opened web-page.
To let you see the new games in bnet status instantly, changing any of your statuses instantly, etc.
Any projects, ideas, offers are welcomed.
