No, I wasn't aware. Thank you for pointing this work out. This is exactly the kind of thing I was hoping for. Wonderful!

I can't wait to see what you have planned.

I was thinking after I posted my comment, that it'd be cool if someone could produce a fuzz tester that used both the specification, and the fact that you can turn the Linux and NetBSD network stacks into libraries (libOS and rumpkernel respectively) and co-engineer/evolve the spec whilst also finding and fixing bugs in both the network stacks.

Excited by what you'll be up to!
