I agree running in 1024 bytes would be challenging.

You're refering to fib_list? It currently has some duplicated code
(this could/should be fixed). Or we could drop it, I suppose, if really
everyone hates it.

(I thought it was a cute idea, but I'm biased :-)

Total it is saving 350k, about 30% of the total text size of the mini kernel
(plus some dynamic savings) with networking.

I would be happy to fix any reasonable objection. But fundamental 
"I don't care about anything smaller than my smart phone" type arguments
are not particularly constructive.
