You can specify different connections in application/config/database.php.  The keys for the connections array can be anything, they do not need to be "sqlite", "mysql", etc.

// application/config/database.php
'default' => 'fred',
'connections' => array(
    'fred' => array(
        'driver'   => 'mysql',
        'host'     => 'localhost',
        'database' => 'database1',
        'username' => 'root',
        'password' => '',
        'charset'  => 'utf8',
        'prefix'   => '',
    ),

    'wilma' => array(
        'driver'   => 'mysql',
        'host'     => 'localhost',
        'database' => 'database2',
        'username' => 'root',
        'password' => '',
        'charset'  => 'utf8',
        'prefix'   => '',
    ),

    'barney' => array(
        'driver'   => 'mysql',
        'host'     => 'localhost',
        'database' => 'database3',
        'username' => 'root',
        'password' => '',
        'charset'  => 'utf8',
        'prefix'   => '',
    ),
),
Then, if you're using fluent queries...

$user = DB::connection('wilma')->table('users')->where('id', '=', 1)->first();
Or, if you're using eloquent, you can specify the connection on the model...

class Dino extends Eloquent {
    public static $connection = 'barney';
}
