Interesting, have you tested this and verified that it works?

AKA: can this play from YT when hosted from a typical cloud provider/VPS?

How do we setup bgutils?

Is it possible to package bgutils into the final jar as part of build/package step in maven (by defining a dependency in the pom.xml)?

Firstly, nope, I don't really have a reliable way to check if it works since I don't have access to a VPS, so further testing is needed.

To setup the pot provider, just go to the releases tab in bgutil-ytdlp-pot-provider-rs, download the .dll/.so/.dylib file (use the one matching your os and architecture) and place it next to the JMusicBot jar file (or, generally, in your working directory), then enable the generatePOT option in the config file. After playing any song and thus reloading the visitor data, a message should pop up displaying the PoToken.

Lastly, the library is in another language (Rust, which is a compiled language and therefore platform-dependent), so if it were to be shipped with the .jar the code would have to extract only the right file for that specific platform, which alone weighs about 43MB. The most feasible solutions are either to have the user download the library manually, or to automatically download it directly from GitHub.
