Communicating
-------------
When one compute process needs to communicate to another, it does so with networking.
The service side is always compute process, but the client can be of two types:
- People (via browser, or perhaps command line tool)
- Compute process talking to another computer process.
Thus, the essential building blocks of any networked system is made up of
