So lots of ram on servers is great when there are many users running many applications, but any individual application will never be able to use all that memory.

It works. Last week I needed to render a huge 3ds max scene with about 75 million of polygons, hires textures, raytraced reflections and global ilumination. 3ds max used 2,7 gb of ram to render that monstruos scene.
