How,
   Sorry I didn't see this until tonight.
I've got a Hermite curve program that outputs '.INC' files specifically for
POV which I use for both objects and cameras.  Input is a simple text file.
Hermite curves are basically a curve specified by directed vectors.
They're piecewise smooth, so the curves are tangent to the vectors going
both into and away from each control point.  It's the way I envision cameras...

Freeware, and example POV code on the website.
