Oli,
   Check my hermite curve generator.  The input files are simple to create
from 3-d coords.

It makes in-betweening simple.  The object pass through the control points,
you specify how many frames to the next control point, and the curve is a 
smoothing function between them.  
At every control point is a vector to which the curve is tangent both into
and out of the control point (piece-wise smooth).

There's example POV source there too...should work great for a Boids sim...
