  New radio telescope arrays offer unique opportunities for large-scale
commensal SETI surveys. Ethernet-based architectures are allowing multiple
users to access telescope data simultaneously by means of multicast Ethernet
subscriptions. Breakthrough Listen will take advantage of this by conducting a
commensal SETI survey on the MeerKAT radio telescope in South Africa. By
subscribing to raw voltage data streams, Breakthrough Listen will be able to
beamform commensally anywhere within the field of view during primary science
observations. The survey will be conducted with unprecedented speed by forming
and processing 64 coherent beams simultaneously, allowing the observation of
several million objects within a few years. Both coherent and incoherent
observing modes are planned. We present the list of desired sources for
observation and explain how these sources were selected from the Gaia DR2
catalog. Given observations planned by MeerKAT's primary telescope users, we
discuss their effects on the commensal survey and propose a commensal observing
strategy in response. Finally, we outline our proposed approach towards
observing one million nearby stars and analyse expected observing progress in
the coming years.
