So far I only tested this in the simulation platform recently, for speed and
ease of use. In the past I've used Nordic NRF52840 USB dongles for hardware
nodes with cBRSKI code.
I'll bring these to the Hackathon.

The Thread Border Router is used: a 6lowpan border router (BR) that connects a
Thread mesh network to Wi-Fi or Ethernet.
This could be manually / administratively set up BR, used for some tests. It
can also be a cBRSKI-capable Thread BR that onboards via Wi-Fi/Ethernet: I also
run a test with that in simulation. The simulator doesn't simulate the
Wi-Fi/Ethernet link but rather "fakes" it by NAT'ting any IPv6 UDP packet to a
preset destination <ip-addr>:<port> to a localhost server [::1]:<port-mapped>
so that the Registrar is reached.
The Thread BR includes a Thread-specific join proxy called "Joiner Router".
Also the "Joiner Router" integrated in other types of Thread devices can be
used: mesh-routers further away from the BR will also support this.

Yes, planning to show the simulator! There's also a step by step tutorial
prepared for it. It would be useful if some people could try the tutorial live
at the hackathon to debug it :)

Agree! It's for proof-of-concept currently. At some point it should get updated
to use secure key storage (via an API to the underlying HW platform).

That's fabulous news.
What is your recommended device to test with?
What's involved in attaching/connecting to ethernet/wifi? I'd guess, an
already connected device with a join proxy, that has 802.15.4+ethernet
connections?

okay, looking forward to this.
Would you like to train others (me) to run the simulation during the hackathon?

okay, that's kinda sad.

okay.
