I think a workshop based format would be best, it's just a matter of finding someone willing to teach.
perhaps WHAT to teach will help guide who might teach it. and that will depend a lot on the intended audience. i am told the fosdem track was geared toward a youngish set, and used, among other things, micro:bits using microblocks. but i am hoping someone who was there could speak with more authority. i am more used to teaching workshops to older entry-level engineers - linux/unix boot-camp, how to live on the command line, install, configure, maintain, ... - ip addressing, forwarding, and building a LAN, - basic routing, way more basic than philip, like rip and maybe simple use of is-is, - how to install and configure a few services (e.g. mail and/or dns) each being a separate full week hands on but this is far too ambitious to start. i suggest choosing a well-defined audience and one subject, teach it once or twice, and learn from that experience. randy
