Had this from a friend :-
"Hi Gina, came across this just now. Looks like there might be a way to run multiple servers on a Pi using different port numbers. www.youtube.com/watch?v=RwKkLniEIIk
Wondered if this could be done with Astroberry Server. Though maybe the reduced software approach would be better. Seems to me that running 3 instances of Astroberry Server on one RPi 4B could be pushing it.
Just ordered an RPi 4B with 8GB RAM for testing. I know I can run Raspbian OS Lite and install 3 instances of indiserver and drivers. That would be a lighter load than trying to install 3 instances of Astroberry Server. I don't need all the apps included in Astroberry Server. The big advantage of Astroberry Server is the ease of installation and setup. I'm happy enough with a piecemeal installation - done it lots of times.
