My concern with it is the excessive overdraw in maps like dm2.
Shaders are obviously a much better solution, as they avoid that entirely, but if you can't use shaders for some reason, there's some interesting code in zquake that projects the sky in 2d-space, resulting in low distortion (about same as with a sky 'sphere') but much less overdraw and thus noticably higher fps.
