Re: Not just 'rural' connections
Indeed. We were doing world-wide video conferencing over a couple T1 channels back in the mid '80s. Granted, the video was a bit crap ... but the audio (which, when you think about it, is the important part, was very, very good. Today's systems are typical modern software bloat, combined with always having to go through a third party for monitoring/marketing purposes.
I see a great need for a simple open source peer-peer video conferencing system.
