The big advantage here is eliminating as much analogue traffic in a system as possible. The Nexo/EtherSound system effectively restricts analogue to the length of wire between microphone and stage box, where it's converted into digital - not to re-emerge again until the signal finally reaches the amplifier - plus of course remote access to, and full control of, all parts of the system therein.
Sharing the stand with Nexo was Auvitran, who support Nexo in this development, providing, for example, the necessary cards for Yamaha digital desks to communicate with Nexo systems via Ethersound. More fundamentally, Auvitran also launched the AVRed-ES - an EtherSound redundant link management device to provide a dual line distribution system for the network. Main feature is A/B real-time measurement of communication quality, and four samples latency on the better link (the RedES monitors and uses the better link at all times).
