We describe an audio service for CVEs, designed to support many people speaking simultaneously and to operate across the Internet. Our service exploits a technique called Distributed Partial Mixing (DPM) to dynamically adapt to varying numbers of speakers and network congestion. Our DPM implementation dynamically manages the trade-off between congestion and audio quality when compared to the approaches of peer-to-peer forwarding and total mixing in a way that is fair to the TCP protocol and so operates as a "good Internet citizen". This paper focuses on the large-scale deployment of DPM over wide area networks. In particular we raise and examine the issues when deploying DPM within the context of large dynamic environments. We argue that DPM paradigm remains feasible and desirable in such environments.
