[xmonad] Actions on window alerts?

Is there a way in xmonad to have actions in response to a window being alerted (when it blinks in gnome-panel)? I'd like to have a desktop to toss instant messaging windows onto to disregard them until the person I'm talking to replies (which causes the window to alert if it currently doesn't have focus) at which point I'd like it to move to whatever desktop I happen to be working on so I'll notice it.
