			The EFF wireless firmware probably intermittently calls [https://github.com/EFForg/OpenWireless/blob/02841f7f4c22bd58e6712b98de05613011076ccf/routerapi/accumulate_bytes this script] which accumulates bytes used in a UCI config file. We could do something similar but with a lua script called by a cron job that simply takes down the tunnel when the quota is reached.

			There is also an iptables module called quota which can automatically enable/disable iptable rules when a quota is reached. It is not clear if it can be used to count both upstream and downstream bandwidth towards one total quota and it also has no built-in mechanism to persist the usage count between reboots.

notes about bandwidth monitoring and quotas

The goal is to find a way to cap bandwidth usage, in and out. The system can apportion the shareable bandwidth to a percentage of total bandwidth available. Here we research how this can be done.
