I am glad to see Contiki getting some "air time" I have been working with this for the past year and I think it has great potential.
One of the great things that Contiki has going for itself is the community. It's very active and growing quite rapidly and it's very welcoming to newcomers.
Is there an equivalent of a terminal in Contiki?
there's a serial console but no shell for it as far as I'm aware - it's mostly just a kernel. there is a nice GUI though if you run it on hardware with video support.
