Having a very quick look, I see a websocket connection, which IE can do just fine.
The only thing I see that it can't is the desktop notification, which you still have some ability, in fact 'pinned' sites in IE let you have a number badge on the taskbar, which is quite good for a chat app, see Skype.
The new web developers generation just replaced IE with Chrome.
