PVP in FFXI right now is not the final, full PVP system. The PVP that currently exists is called Ballista, its a game form of PVP implemented so the developers can get a feel for this type of system in the game and so players can adapt to and try it out. Ballista is PVP as well as RVR, whereas the 3 nations of which your character can belong to will battle against each other. You pay a fee to enter, and the winners get Conquest Points for your nation in the area you fought, as well the pool of money from people entering is given to each member of the winning nation.

Basically its two nations at a time, and you'll run around in a capture the flag type game. You uncover orb thingies around the area and your goal is to shoot these orbs into the opposing nation's rook statue thing. You gain points for every successful one, you also gain points for every opposing player you kill. I haven't actually played it yet but I hear from most people in my Linkshell that it's very fun. I'd think that the release of the new expansion this fall will expand on this PVP system a lot more, so until then Ballista is just a fun alternative.
