Morning to do this you need to implement some kind of quota system. In essence you need to rotate your logs ( hourly, daily etc) and then put some little script together that adds up the traffic associated with each user account. This can then be used to feed an ACL denying access. The implementation of the acl can be as simple as a text file, or using external ACLS you can query a DB.
