I plan to have multiple node-red servers running. There will be, most likely, a main server that needs to collect data from flows running on the other servers.
Any pointers to reading on setting up such a thing?
Or, hints, etc.?

What will the servers be doing?
typically things like providing data on my solar hot water system.
But other things like home sub-systems control and monitoring.
Use MQTT to send info back and forth. Here is a link to a description of MQTT https://www.hivemq.com/mqtt-essentials/

All my Pi running Node-RED use MQTT to pass info
Definitely MQTT. I have 3 Node-red installs (Ubuntu, Pi3, Bluemix), and they all talk via MQTT (Mosquitto), as do some of my other home-control devices. It works flawlessly publishing JSON (as strings) - I'm not sure how easy it would be if you had binary content coming from your devices.
