I tinkered with this last year. It's kind of neat, but doesn't seem "reliable" (of course it is free...so one cannot expect commercial grade), it seemed to drop out and disconnect whenever it wanted. Tried it on 2 PC's on different networks, and on my smartphone. Looks like everyone that joins makes their own channel, but not a great way to really figure out what is what. I was interested in using it as a link for: 1. Pushing my scanner audio to it to create a private stream for mobile use on my phone. or 2. Interfacing it with a UHF portable so I could use my smartphone to link to my PC/UHF and it would work my repeater. Tried 1, wasn't consistent. Didn't get around to #2.
