Hi adgwytc,
In an L2TP scenario, between LAC and LNS it will be tunneled encapsulated traffic between the loopback of the two (LAC n LNS) as source and destination address.
Yes, if would like to have CoS on bi-directional traffic, then you will need to have interface considered as both ingress and egress and have cos policy in accordance with traffic flow direction you are modulating.
If your requirement is for CoS for individual subscribers, then probably you will need to look at hierarchical-cos for subscribers.
