I don't think you can attach it already to something else than a network interface. But maybe it could be extended to run against a channel provided by some slirp 2.0. > * UDPv4 port forwarding > * TCPv4 port forwarding Including forwarding from the guest to host-side chardev backends. > * SAMBA integration And all this (almost) fully configurable. Yes, it's a lot of stuff, much more than even a talented student could complete in a single GSOC. I'll try to specify a reasonable, possibly scalable task.
