Set logging path/file to use php://stderr

Question

I'm rethinking our Craft environment/workflow. My idea is to accommodate disposable and/or multiple container (or server) environments. As a result I want to use log aggregation apps like papertrail, logstash, etc to consolidate and investigate logging across multiple servers. They recommend logging to php://stderr. Is this possible? What approach would you take to override the apps log route?

Pretty sure you'd need to write a plugin that has a class that extends Yii's CLogRoute and override the processLogs method with your own logic. Something like this:

class StdErrRoute extends \CLogRoute
{
    public function processLogs($logs)
    {
        $strErr = fopen("php://stderr", "w");

        foreach($logs as $log)
        {
            fwrite($strErr, $log[0]);
        }

        fclose($strErr);
    }

}

Your plugin's init() method would register the route via craft()->log->addRoute().
