Include device discovery in protocol definition

[repentsinner]

Many device management systems (aka vendor apps) have a mechanism for discovering devices on the network without having to manually type IP addresses, but the implementations used are:

1. widely varied,
2. sometimes home-brewed solutions that don't account for significant available/tested standards 🙄😬😤,
3. quite often out of date, if they do use a standard

It would be great if we could recommend a modern, off-the-shelf, easily tested & integrated mechanism for devices that want to conform to the standards we are developing here. See for example dns-sd or ssdp.

This seems out-of-band relative to the actual data/metadata fields we have been working on lately, but IMO is just as critical to achieving efficient, error-free on-site workflows.
