Turning on output buffering in a wordpress plugin

Although I realise this is probably not the right way to go about it, I managed to turn on output buffering using the following code in my plugin:

add_action('init', 'rsq_buffering');
function rsq_buffering()
{
    ob_start();
}

I probably should be doing any session stuff from within the init hook instead of just all over the place.
