I know people who regularly used this for rehearsals during the pandemic (maybe they still do). I told them about it when it was previously featured here. They were thrilled. These were people that used to meet locally, so presumably the latency was relatively good.

Another group was interested, but the setup was too complicated for them (wired ethernet, messing around with asio). But if you can get beyond that, it's apparently pretty great. There might be a product idea there, a plug and play solution that avoids the manual setup.
