The first zone player of claim 7, wherein while performing the master device role, evaluating one or more operational performance metrics of the one or more processors or the at least one network interface indicating potential degradation in performance of synchronous playback of information content by both the first and second zone player comprises the first zone player determining that at least one of the one or more processors of the first zone player is overloaded. 9. The first zone player of claim 7, wherein the one or more operational performance metrics comprise a network latency metric, and wherein while performing the master device role, evaluating one or more operational performance metrics of the one or more processors or the at least one network interface indicating potential degradation in performance of synchronous playback of information content by both the first and second zone player comprises the first zone player determining that migrating the master device role from the first zone player to the second zone player would improve latency of message transmission within the synchrony group. 10.
