Query: Commensal, Multi-user Observations with an Ethernet-based Jansky Very
  Large Array   Over the last decade, the continuing decline in the cost of digital computing
technology has brought about a dramatic transformation in how digital
instrumentation for radio astronomy is developed and operated. In most cases,
it is now possible to interface consumer computing hardware, e.g. inexpensive
graphics processing units and storage devices, directly to the raw data streams
produced by radio telescopes. Such systems bring with them myriad benefits:
straightforward upgrade paths, cost savings through leveraging an economy of
scale, and a lowered barrier to entry for scientists and engineers seeking to
add new instrument capabilities. Additionally, the typical data-interconnect
technology used with general-purpose computing hardware -- Ethernet --
naturally permits multiple subscribers to a single raw data stream. This allows
multiple science programs to be conducted in parallel. When combined with broad
bandwidths and wide primary fields of view, radio telescopes become capable of
achieving many science goals simultaneously. Moreover, because many science
programs are not strongly dependent on observing cadence and direction (e.g.
searches for extraterrestrial intelligence and radio transient surveys), these
so-called "commensal" observing programs can dramatically increase the
scientific productivity and discovery potential of an observatory. In this
whitepaper, we detail a project to add an Ethernet-based commensal observing
mode to the Jansky Very Large Array (VLA), and discuss how this mode could be
leveraged to conduct a powerful program to constrain the distribution of
advanced life in the universe through a search for radio emission indicative of
technology. We also discuss other potential science use-cases for the system,
and how the system could be used for technology development towards
next-generation processing systems for the Next Generation VLA.
