I mentioned meet.coop and their hosted Big Blue Button service in that other thread, and said that Open2020 had been able to handle a fairly large number of people.
Here’s a more critical report. https://www.loomio.org/d/knxKE1pL/next-generation-room-services-and-stewarding-of-digital-tools-infrastructure
If you can’t access that, ask for admission and I or somebody will let you in.
But here’s the TL;DR version:
meet.coop is working hard on formulating its service offering in the light of hands-on piloting, and is constrained as a start-up by (human and financial) resource shortages, small-coop economics, practicalities of coop-to-coop federation and shortcomings in the available software (eg the front-end for administering bundles of rooms). Thus, the service at first will be of an early-adopter Alpha-release nature, and users will need to be ready to go through a bit of a learning process in how the coop membership works, and how the service evolves and becomes richer.
…the current server provision (Koumbit coop, Montreal) is good, so long as lots of users don’t go crazy with big rooms and lots of cameras on. As revenue comes in, load balancing across multiple servers is part of the roadmap. All good.
The BBB tech itself works, no problem, the challenges are more about the large-scale administration of the front end, as a user-facing platform and a paid-for service. A BBB room works fine (depending on browsers being used and of course broadband connections) and quite large numbers can participate (with cameras off, preferably). If an organisation just wants a virtual space to meet in - especially, in smallish teams - a BBB room will do the job (in a slightly different way than Zoom/jitsi but the learning curve isn’t too great). At this stage, with regard to meet.coop (there are other providers of BBB access too) the issue is more about wanting to contribute to the coop project per se, and engaging the challenge of putting core infrastructure in the commons, rather than in corporate hands. Being a commons-cooperative federated venture is a big part of the proposition.
