I really think that you're misunderstanding POV.  The look_at vector is 
precisely that - the point that the camera looks at.  Now, if you want the 
object the camera is looking at to be not in the center of the picture, 
then whatever *was* in the center of the picture would be the new look_at.

For example, say we have this:

/---------------\
|       |       |
|       |       |
|       |       |
|-------X-------|
|       |       |
|       |       |
|       |       |
\---------------/

Now, let's say we want to move the X to here:

/---------------\
|    |          |
|----X----------|
|    |          |
|    |          |
|    |          |
|    |          |
|    |          |
\---------------/

look_at should no longer point at X, because the camera is looking below and 
to the right of X.  Then, the new look_at would be O:

/---------------\
|    |  :       |
|----X----------|
|    |  :       |
|::::|::O:::::::|
|    |  :       |
|    |  :       |
|    |  :       |
\---------------/

This is what you want, right?  Then, make your look_at O, not X.

Hope this made sense :)
