That should be easier to write and keep platform independant, too. And 
more likely to get working right...
How do you plan on doing different camera types? As far as I know, 
OpenGL only does perspective and orthographic projection. You might have 
to issue a warning when another type is used and use perspective 
projection in those cases...that shouldn't be a problem for quick 
preview renders.

Practical reasons: it could make it easier to get camera position/angle 
and general lighting right, but it really would be the job of a 
third-party modeller.
