Didn't really want to put this in the code gallery since it's nothing fancy what so ever, but I figured it may serve some use to someone eventually.

PHP Code:

function onCreated()
{
  // -- START EDIT
  temp.objectList    = allplayers; // List of players to process
  temp.numberOfTeams = 2; // Number of teams
  // -- END EDIT
  
  temp.playerList = new[0];
  // Generates a new list of objects we can work with
  for (temp.object: temp.objectList) {
    // Let's avoid adding those silly RemoteControls
    if (temp.object.level.name != "")
      continue;
    
    temp.playerList.add(temp.object);
  }
  
  // Amount of players
  temp.amountOfPlayers = temp.playerList.size();
  // Array creation based on number of teams
  temp.teams           = new[temp.numberOfTeams];
  temp.team            = 0;
  
  // Do we have enough players to make even teams?
  if (temp.amountOfPlayers%temp.numberOfTeams)
    temp.oddManOut = true;
  
  // Let's add players to the teams!
  while (!temp.teamsGenerated) {
    // Grab a random player from the list...
    temp.object      = randomString(temp.playerList);
    temp.objectIndex = temp.playerList.index(temp.object);
    
    // Abort if an object wasn't found anymore
    if (temp.objectIndex == -1)
      return echo("[" @ this.name @ "]: Index of object returned -1!");
    
    // Add the player to the team array
    temp.teams[temp.team].add(temp.object);
    // Remove the player from the player list
    temp.playerList.delete(temp.objectIndex);
    
    echo("[" @ this.name @ "]: Added '" @ temp.object @ "' to team '" @ temp.team @ "'!");
    
    // Based on how many players are left, we may stop now.
    temp.remainingPlayers = temp.playerList.size();
    if (temp.remainingPlayers == 0)
      break;
    else if (temp.remainingPlayers == temp.numberOfTeams - 1 && temp.oddManOut)
      break;
    
    // If we do have more players to work with, change the team for the next one.
    temp.team ++;
    temp.team %= temp.numberOfTeams;
  }
  
  echo("[" @ this.name @ "]: All" SPC temp.numberOfTeams SPC "teams sorted evenly!" SPC temp.remainingPlayers SPC "player(s) were left out" SPC (temp.remainingPlayers > 0 ? ":(" : ":)"));
} 


All you really need to do is provide a list of players and determine the amount of teams, and it'll do the rest of the work for you.
