I wonder how hard it would be to build one of those zooming google maps. How much data is it in total? Currently my search index is 5.9 gbs which is crunched down to 30 mb so that it can fit in the server memory. The problem of memory management does seem to dissuade developers especially when cloud is so easy to get into but it leads to a even bigger problem of them not knowing or having vague knowledge of how these systems work.
