A point of interest: I've been able to run the Throwing System on one machine with VTube Studio on another. In this setup, I'm running the System on the same computer as OBS Studio, then connecting the VTS API traffic to the computer which is actually running VTube Studio, which itself sends its output back to the OBS Studio machine via NDI. You just need to make sure that the computer running VTube Studio can accept connections from other computers on the same subnet.
