Warhawk player, then you might want to check out MyHawk.org. The fan site, in collaboration with developer Incognito, tracks in-game Warhawk stats and has just undergone a major update which added in new stat features such as: "clan matches & tournaments, daily leaderboards, new graphs, per-weapon stats, stats on individual games, [and] game calendar."
The game's director, Dylan Jobe, revealed on the PlayStation Blog that this is all possible because of a little experimental XML feed. The XML feed streams raw Warhawk data, which any community -- not just MyHawk -- can get access to. Jobe calls it the "democratization of the player community." That means if you run a Warhawk community and want access to the global feed, Jobe says to "hit the Warhawk forums and post your info."
