[mesh-talk] LATE!

I am so late. I've been sick since last Thursday and have made little progress since Thursday. I will show up before 2100 hours, order a pizza and commence swlib hacking. btw does anyone know much about serval mesh? I'm wondering if it makes sense to make every node a serval mesh gateway or if it will just be a useless resource hog. also, i had a weird idea: I believe cell phone speakers are capable of making noises above the level of human hearing (though unfortunately not above the level of dog or cat hearing) and i was thinking about the GPS method of repeating a signal below the noise floor and then using auto-correlation at the receiver to bring it back above the noise floor. I'm wondering: Would it be possible to transmit using this method over fairly long distances using just the audio input/output of a smartphone as long as the bitrate is low enough? Could we multiplex multiple signals without centrally assigned gold codes? Could this be used to make a jamming-resistant low-bandwidth mesh for e.g. decentralized messaging in a disaster scenario? How much would this affect animals? -- marc/juul
