Interesting, thanks for the links/info.
I've spend the last 10 years performing remotely and occasionally in real life (meatspace!) as well, so know well what you mean.
I've experimented with a variety of virtual collab methods, from performing live internationally networked performances as cartoon buskers in SecondLife (https://www.youtube.com/watch?v=XVHoNhiowVA&list=PLD3F02305D166CEC4 ) to asynch collabs on platforms like Kompoz and others.
They all have their pros and cons, just like RL performances.
One thing I've found performing live virtually (thin emotional bandwidth channel as it may be) is that even having one person listening and chatting on the other end of the wire puts you in a performance mode that's mentally different from playing to an empty room. Mediated performance by avatar is also very different from streaming live video performing as well. Which is very different again from full bandwidth real life gigs.
All good imo, and a lot more room to explore as the tech gets better.
I'd love to get an RL band together again though!
