Pianoteq in band remotely over internet with Voice Meeter + Jamulus ?

My jazz quartet (drums, bass, piano, sax) has been using JamKazam to play together over the internet, with me on Pianoteq. Also free, it seems to use a peer-to-peer strategy to connect each of the players, instead of the client-server strategy used by Jamulus, so there is no server to set up and maintain. To keep total gear and internet latency down to 25ms or less, which feels acceptable for playing in sync, each player needs a direct Ethernet cable connection to internet modem/router (not WiFi), a low-latency audio interface, and fast internet service. We are fortunate that we all live within 20 miles of each other, so internet latency is not a problem, but I have joined JamKazam sessions up and down the US West Coast with success. It can sound like playing together in a recording studio, with headphones on.  Pristine sound. You can turn video on and off for chatting. JamKazam is a work-in-progress, and some bugs are still being fixed, but it has been wonderful for us.

There is no need for additional software. JamKazam recognizes the inputs and outputs available in your audio interface, so any sounds your computer directs to your interface are available to your JK stream and to your headphones. Our group members have a variety of Macs and PCs and a variety of audio interfaces, and they all play nice with JK.

When you activate video in a JK session, it enables menus for control over video resolution, frame rate, adjusting sync of video to the audio, and more. You can designate an external video camera, or use the camera in your laptop.  You can record audio and video within JamKazam. Depending on internet traffic and the quality/bandwidth you have from your ISP, you may find that activating the video stream interferes with the quality of your audio stream, or that video lags too much from your audio stream to bring into synchrony without creating an uncomfortable lag for both. However, on a fast connection on a good day, it's like being in the same room. I am not an expert, but I think the advantage of the client-server model used by Jamulus is that everyone is on the same centralized clock provided by the server, while with the peer-to-peer connections, players can tend to adjust progressively to slight latency time lags back and forth, until they add up to a problem.  JK provides a distributed metronome that you can initiate at time zero, if this is an issue.  We've always remained synchronized enough that it's never been an issue.  However, unless you are on a dedicated network, I think you have to accept that latency will always be a little at the mercy of the particular routes the streams take through the internet. At present, it seems good for rehearsals and sessions, but not tight enough for professional live performances.
