Thinking more about that, JRemote communicates via MCWS, I think, and if I'm correct, that's not the same communication channel a theater view client would use... Am I still correct here?
If I am, I don't think there'll be any issues here if authentication is enabled.
The other issues are with true library clients that are merging changes back into the library via "delta" archive files, which wouldn't be the case with something like JRemote 😊
