Or we can write some articles? Or reach out to school systems? Or? I've been fiddling with jitsi, and am about to give freeswitch a try. Last I looked freeswitch's otherwise pretty nifty conference bridge didn't dynamically adjust at all due to e2e signalling, but that was years ago. (?) I have to admit that p2p multiparty videoconferencing seems more plausible in a de-bufferbloated age, but haven't explored what tools are available. (?) There's also been this somewhat entertaining convo on the ietf mbone list: https://mailarchive.ietf.org/arch/msg/mboned/2thFQk_IYn38XCZBQavhUmOd= 6tk/ Around me there has been this huge interest in "streaming". The user agreement for these (see restream.io's) is scary - and the copyright police have control... but I am very happy to report that even a couple really lousy long distance fq_codel'd ath9k links work *really* well (with facebook's implementation), where a non fq_codeled link (ath10k) failed miserably... and setting up a reflector in nginx also failed miserably. Anyone working on the ath10k AQL backport for openwrt as yet? --=20 Make Music, Not War Dave T=C3=A4ht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-435-0729
