This -may not work-. I've tried it on my site, and I thought it worked, but it interfered with other areas of my site and I took it down until I can find the problem. I used that code on 1.1.x with no problems and did some quick/nasty hacks to get it to 2.0, I'm sure it could be better and there's probably some redundant code there, but hopefully it's a start for someone.
