Well current approaches really all boil down to a network device in guest passing us raw packets. Typically this means the backend deals with raw packets as well. For example, macvtap injects raw packets into host device, That's a priveledged operation. For tap you can setup NAT to reduce the priveledge. This is at the moment far from stateless though. I would love to see something that does NAT but does not need priveledges or host state. qemu uses slirp to do (most of) this in userspace but it just seems silly to maintain yet another networking stack just for this.
