But the distance I want is the distance between the camera and the
closest point on an arbitrary geometric surface behind the target. Now
maybe the easiest thing to do would be to snap the target to said
surface and get that distance. But there again, I need to identify the
position in space where the ray from the camera intersects that surface.

Hey Tim,
I would use a expression.
open the exression editor-->Function-->Distance-->distance to camera
the result would be something like
ctr_dist_cam( null. )
null. would be the object name you're using to mesure the distance.
hope that helps

I'm trying to set up a camera rig that will let me use an item of
some kind (null, curve...) to act as a kind of focal point that can
be moved around the frame. Basically I want to have a control
parented to the camera which I can move around the frame, and which
can be used to create a vector between the camera and whatever
surface is "behind" that focal control. I'd then get the distance
between the camera and that point on the surface and pass that to my
lens shader.
I'm really a noob when it comes to ICE in general, so I'm wondering
how best to do this. I suck with vectors...
