To catch-up the rest of the list.  The overwhelming feeling on netdev 
was that we should just use TCP to communicate from the guest to the 
host instead of a special userspace transport.  By using slirp to handle 
TCP within QEMU, we can expose the traffic to elsewhere as just a stream.

Eventually, we'll add stuff to the distros and possibly to virtio-net to 
make the guest visible network adapter that is connected to "vmchannel" 
an isolated network from the rest of the guest networking stack, 
bypassing iptables, etc.  This will make it always reliable.
