I saw that video that Notch posted to show how map are generated.
As you can see, the map doesn't seem to lag and load much. It appear so quickly. Is it possible to load a map that fast on SMP, any compression possible to achieve that ?

I'm fairly sure (not 100% so don't sue me if I'm wrong) that that video was sped up and he actually was flying much slower over the terrain, but sped it up to show it off in a shorter video.
