Oh, does the RNode firmware support v3 now? If so, nice. I was looking at playing with those, but at the time they only supported v2 and all I could buy were v3.
Oh there's plenty, nothing on my local RNode yet but lots of random people and pages on the different reticulum interfaces tunneled over the internet and i2p.
