You can do it through scripting. Monitor amount of traffic for each user in scheduled intervals, and when user reaches limit add his IP to address group. Set rules that block Internet for everyone in that group.
Better, you can forward every outgoing connections to TCP port 80 to your local http server which would show informational page about reason for blocking internet access.
