Hi all. Has this wonderful DAC/streamer. However, client side python script is crap at best.  Worked on improved version. Please test and share feedback!

You should attach a FOSS license to your repo and in the .py code headers so the files can be legally redistributed. I think the original Allo script is GPLv3
