> I'm gonna run some tests this weekend to see if and how I can set up OBS to record the stream.  

It is fairly straightforward, only catch is, if you want different stream and recording quality, you need to have the appropriate horsepower, there is one config menu for stream , one for recording... later on the main screen you just hit "start streaming" and "start recording" buttons and it will do both...

I can help you thru screen-share if you run into issues, ping me directly if needed (UTC+1 timezone).
