One of my colleague had the opportunity to talk to Kate Steward about
that and David Miller told her:

  Kate, I have just started assembling the technical committee for the
  networking track and once that is done we will discuss how we want to
  handle submissions.

So it seems safe to wait for this Networking CfP!

Thank you for this, that will be useful!

Oh, you spelled my name Mattheiu, that's probably why we were not
accepted... :-D (no worries ;-) )

Good point :)
I think we also sent it just before the end of the submission period and
we just had a talk about this topic at Netdev 0x12 about this.

I hope we will be able to say here that before September, RFC patches
will be sent to netdev ML.

Matt
