Network service driver support

Would it be a lot of effort to port the NUL Intel NIC driver to NRE? And/or to implement a bridging functionality between VMs when no physical card is present?

It shouldn't be that hard. You just have to implement the NICDriver interface and use NetworkService::broadcast for received packets. I haven't done that yet because I don't have one of the supported Intel NICs. So, if you do, feel free to port it and create a pull-request :)

I think, implementing a simple bridge would be easy as well. That is, a bridge where all outgoing packets are simply broadcasted as incoming packets to all other network sessions. But of course this is quite limited and for a real implementation the question would be how one can configure that, i.e. for example VM1 talks to VM2, but VM3 talks to the outside world.

As always, I would love to do that, but unfortunately I can't because of legal reasons. But as a first quick fix I might be able to use a bridge like the one you explained.
