[Babel-users] A Babel implementation in Go

[Andrei]

Hello, Steffen.

It's a very cool and interesting project.
Being a network admin, I would be very interested in such a use-case,
when it will be at least beta-status ready.
So, I will be able to assist with some testing of routing. (Playing
with some overlay things too, multihop and RTT based.)
But unfortunately I am useless as a programmer.

Andrei.
