Works extremely well, support for multichannel streaming, passwords and also very easy to setup.
If you only use it for checking how a mix sounds on a smartphone it is worth the download. I can see myself using it for collaboration with people/groups. I have a project now that has 2 people "signing off" on tracks and right now I use the old bounce, send email, wait for the 2 to get together (lives in different parts of the country) and get back with comments, make a few changes and send again. With this I could easily setup a meeting and fix the small stuff in a fraction of the time.
Yes, I'm aware that this technology exists, but this is open source, and free (because I'm cheap)
