I evaluated this border style some time ago. And I must say I still prefer the original behavior of dwm. The problem about you're borderstyle is, that my brain needs more time to identify the selected window. Also I don't use resizehints, as some clients really start to fuck up if it's set to false, which is even more counterproductive with this patch.
Oh, I'm new here and didn't realize that someone already tried this before. I didn't see it in any patches or screenshots.
I only have terminal sessions managed by dwm, and rxvt-unicode is set to dim windows that are out of focus, so it works for me. I'm typing this in Apple Mail, and I'm thinking that maybe what I really want is a drop shadow around the active window instead of borders...
