title: Limiting Membership By Bandwidth
body: <p>I've just deployed a Codeigniter application to Amazon EC2 (using S3 for media and RDS for MySQL).</p>
  
  <p>I need to restrict user account access based on the amount of bandwidth used - accounts will be based on bandwidth e.g. Basic account £x for up to 20GB per month etc.</p>
  
  <p>However I've no idea what the best way to do this is. </p>
  
  <p>My EC2 instances are Ubuntu with Apache2 if that helps.</p>
  
  <p>Any ideas appreciated!</p>
  
  <p>Thanks!</p>
