"Intercept Charge (Combat, Teamwork)
You can get in the way of an opponent charging your ally.
Benefit: When an opponent charges your ally with this
feat, as an immediate action you can move up to your speed
toward any square in the path of the charge. If you end
your movement in the path of the charge, the opponent
must stop when it becomes adjacent to you and then attack
you instead of your ally. Your movement from using this
feat counts toward your movement on your next turn."
IF you move into the path with a reach weapon, would you get an AoO? What if you moved just adjacent to the path? It seems to me that this could become a very INTERESTING feat for goblins to have.

If you take the rules exactly as they are written, it says that you can move up to your speed towards any square in the path. So you can stop in an adjacent square and then perform an AoO while the opponent just charges by.
Edit: Note that the opponent only has to stop when you end your movement in the path of the charge, meaning AoOs also work with non-reach weapons.
