*keep ranting on about how ClusterGroups would save the day*
I think we should have some kind of paging out--just something very flexible, because I don't know about you guys but pretty soon I won't be able to run AhraPahts because I only have 512MB of ram (if it won't fit into that, i'm sunk). When people add more content--unless we make harsh rules about numbers of faces/shell--it's going to grow to a horrible size. I think the trick would be to have the shells be illusions, let me explain.
You have district, then it has python controlled object vis. So, you go to the end of a district and then it warps you to the next one(there are only two of these districts) and sets the apropriate vis things (ie. make visible the wall at the end of the street, make visible the super-fountain) then page-in only the fan-content. This will lead to a quick warp and only a minimal loading time for the fan stuff.
Using this idea you could make an endless maze, the only things that would have to be decided would be your rotation and your entry-point.
Welcome to the quantum world, AhraPahts.
