LinuxMusicians

So when you have such a live collaboration, can there be an audience that can listen ? Much like a webminar, but less boring. Invitations are sent for a webminar, people register, and then the event takes place with people listening. Is it the same with inet music live collaborations ? I understand that the audience would be listening only as the music will happen only between the selected musicians (in a webminar anyone can ask questions).

The musicians would also have an audio channel just for themselves so they can exchange between them outside of what the audience can hear.

A live concert in your home with musicians jamming (or playing their pieces as in a concert) that are located a bit everywhere.

There is the possibility to listen to live as well as to the past sessions.
You can also run your own server, which will not be shown on ninbot.
Is that what you're asking?
