Back in 2002, the FreeS/WAN project moved from STU-III phones (I had two of them with a two-line conference phone, so we could have three locations connected) to H323 over IPsec [dog fooding]. Of course, each meeting started with 15-30 minutes to debugging: when IPsec didn't rekey right, we'd often wind up with unidirectional communications. (It was a very good way to debug dog food issues) A point that ||ugh made at the time was that he didn't think that we it was actually useful to be in radio mode: that all of the subsequent digital systems were designed to emulate the properties of the radio, which was that the *general* as allowed to shout lounder than everyone else until they all shut up and listened. The question was our conferencing systems couldn't just accept audio from each participant, put it in a queue, and play it out. Some participants might hear comments in different orders. I don't know if anyone has tried this. It seems that such a system would be useful for in a Earth/Luna conference where speed of light delays are 1-2s. Beyond that, one gets into sending video-grams as one sees in Expanse. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | IoT architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [
