So ride by attack:
When you are mounted and use the charge action, you may move and attack as if with a standard charge and then move again (continuing the straight line of the charge). Your total movement for the round can't exceed double your mounted speed. You and your mount do not provoke an attack of opportunity from the opponent that you attack.
Pounce:
When a creature with this special attack makes a charge, it can make a full attack (including rake attacks if the creature also has the rake ability).
Format: pounce; Location: Special Attacks.
So a lion that is mounted could charge with ride by attack get a full attack with pounce while the rider makes a spirited charge and still move pass the target (without provoking AoOs) to do it again next round?

Aside from the difficulties inherent in actually using Ride-By Attack, yes. Keep in mind that you have to both obey the normal charge rules (most importantly, charging to the closest square) AND continue the straight line of the charge.
It's pretty difficult to actually do both of those things in practice.

Granted, having a mount with nimble moves and acrobatic step will help some, as would grabbing some of the last wall feats.
Another thought: How would the Duelist charge abilities work on a mount (if at all)?
