I think the problem you are having is because focus information is
handled at the X and window manager level - I don't think emacs knows
anything about the focus. Note that this is just a guess.
With the right window manager, it is certainly very easy to get access
to this information from within Emacs. But I'd assume that there are
also some cross-WM methods... after all, all WMs know which window has
focus. (Yes, this assumption involves a bit of a leap of faith on my
part.)
