I did some more digging, and I think I found an open-source project that might surpass Wimba in terms of features and ease of use. Is a locally hosted product an option? This seems to just use the web browser as a client (nothing for users to download).
I’ve done more research into Google Hangouts, and it looks like this just isn’t going to work for our group size – apparently we either have a 10-person video limit, or we pay to get a 15-person limit (which is still rather low), or we go to text-only chat, in which case we might as well be using IRC.
So we can either go back to Wimba, go low-tech and use IRC, or investigate other options.
For tomorrow’s call, I propose continuing with Google Hangouts since it seems rather last-minute to change, but we can fail over to IRC if the call fills up. IRC connection information can be found here:
Let me know if you have thoughts/questions.
