I started thin Thinking about this all over again lately now that all the easy to mod minecraft clones are popping up, voxel.js or python minecraft in 500 lines for examples. In a minecraft environment it would look a bit less like a employee playing a game and the possibilities are really helpful if you think about them, virtual server rooms you can actually walk into, punch a rack and get a menu, actually punch a connection to take a node offline. Wouldn't mind a way to physically see memory and cpu usage of processes mapped to the size or color of objects in this type of environment either.
