I assume "domain" here doesn't refer to domains in DNS terms. Do we need to
separate this code in a directory separate from remoting_service.h?

I am using domain in the 'domain model' sense:
https://en.wikipedia.org/wiki/Domain_model

These are the objects that are a result of an API call that an application might
want to keep around to update state. I assumed this was a common term.
