Hi Ron, thanks for taking an interest. : )
The object (in the original shot that threw this up) is a plane attached
to an axis, generated from Syntheyes. The shot was tracked so that the
front of a subway car could be simply altered, by projecting an edited
version of the plate onto it as it pulls out of the station and past the
camera.

PS. I will check to see whether Howard's scripts can be used to help
with this kind of thing.

This object, where does it come from?
Are you generating it in Nuke? How are you moving it?

So, no comments on how to stick a camera to an animated axis (or
object) and have it maintain its relationship with it?

Having thrashed around for a while trying to get a camera
linked to a moving object, I'd be really happy to be shown The
Way.
The idea is to get a camera (which is projecting an image,
often some edited version of the plate) to keep it's position
relative to the tracked object. This is a natural behaviour
in 3D software such as Maya/Max, but not in Nuke it seems. In
Nuke the linked object inherits all transforms of the object
from [0,0,0] and I scripted my way beyond that, but the
rotations are where my attempts have fallen down. I will
plunge in and learn more about matrix transforms if I must,
but if there is another way I would be so grateful.
