Capped acounts on mikrotik

Hi all.

I hope this can be done, we are busy starting a small wireless ISP, the server is finished (Router OS) but we need to give clients capped accounts. The uncapped is not a problem.
The clients must have a way to see how much bandwidth they’ve got left via a link in a website.

I need help setting this up if possible. If not, does anyone know what Linux server I can use?

Thanks.

The clients will connect via pppoe.
