Virtual texturing is a much cooler technology than clipmaps though. It's got
finer granularity, is (oddly) easier to implement, and has a wider
application.

Now we just have to wait for more than one IHV to implement it. It's not the
new lensflare, but it is the new bumpmapping, in that it's cool tech,
everyone agrees it's cool tech, but it'll take ten years after it was shown
to work to get mainstream use :-)
