Project Darkstar → Darkstar multi-server coming along, as this video shows
John from the Darkstar forums (and project team member? I’m not sure), has posted a short video of Keith Thompson (one of the Project Darkstar Server engineers) showing a demo at 2009’s Austin GDC. The video is a bit hard to watch if you’re sensitive to shaky motion, but it’s worth it if you’re a big enough geek, like me. 
Apparently, the Snowman demo game is running on two servers, and the load can be dynamically managed so that if one server reaches a limit, clients will be moved onto the second server. Interestingly, this means both clients that are logging in and clients that are already in the middle of a game. The load is balanced transparently by Darkstar, with clients continuing without a hitch.
Looks like they also have some decent monitoring tools. I wonder if those will get released to the community?
I wish them all the best, because I’m using Darkstar for most (possibly all) of my future games. Go Darkstar team!!
