Feedback on webrtc prototype: persistent (and anonymous) group audio in chrome

What it is: www.gabberly.com .... Free group audio prototype that requires no sign up, user ID or software -- other than Chrome. It's mostly built on WebRTC.

My question: Is this useful to anyone but our dev team?

How to use: Click Create Conference button on www.gabberly.com. Share resulting unique link with 1 or a 100+ friends. Anyone who clicks is instantly joined to live audio conference. Group members drop in/out of conference through the day, stay all day, use for a quick together, etc...

Requirements: Chrome + computer with mic/speaker. (No registration, sign up, personal data...)

Why we made it: Keep our team connected on a particular issue, without having to worry about Sykpe, Google IDs, or setting up bridges
