LPC: Making the net go faster (Briefly: user-space network queues)

The idea behind network channels is to push (packet) processing out of the kernel towards the application. Over simplified: a direct pipe between incoming packets at the hardware level and the application. Packet processing won't be done by the kernel (again, oversimplified), hence no firewall checks.
Firewalls would have to be implemented in user space, in e.g. a library, every application connecting tot a network channel would need to link to that library and explicitly do it's own firewalling.
