It is interesting that an idea of a user-space IP stack is useful not only for tiny systems, but for those that wants to handle 1e6 connections with minimal latency. Perhaps indeed the extremes can not be handled by a common stack in the kernel.

Done at least here: http://www.shenick.com/products/diversifeye/ ; possibly also elsewhere.

Luigi Rizzo's netmap goes that way: http://info.iet.unipi.it/~luigi/netmap/

I think such an approach could be a solution for the problems mentioned in the article too. I mean to implement some kind of lightweight kernel interface between NIC and userspace. Than user would be able to disable kernel networking and use his own userspace networking stack (either tiny or performance-oriented one) in extreme cases.

that's already available, that's what LWIP is that Andi mentioned in his original post. It's not that small, and it only takes a few apps before it becomes larger than the kernel version (and only a couple to be larger than Andi's stripped down version)
