Well, it doesnt look as nice as the hack we had for 3.0.7, but we'll manage untill someone ports it over as a plugin for 3.5.

It uses eggdrop and is installed as a plugin. It grabs the info from a .txt file that is uploaded to the same server where our forums runs on every five minutes, after which it is exported to the extra who's online table we created for it. We're still tweaking it as we speak, since the forum link I've just posted is our new work in progress forum which we will use to update our current 3.0.7 when its fully done.
I've asked the coder who made it if he is willing to release it publicly, but he doesnt really want to spent lots of time helping people configure it. :ermm: If there is a huge request for it, I could ask if he is willing to release it though.
