Can't you use a non-routed interface just for this purpose? That's not
very different from having no network.

Ultimately you need some kind of channel for the data, and at the moment
your options are:
* unix domain sockets
* TCP sockets
* the stdin/stdout proxy process used by the ssh mode (which could
conceivably be re-used for some other process based transport)

We have plans to support KVM's AF_VSOCK for this same purpose:
http://xpra.org/trac/ticket/983
But AFAIK, this isn't supported with VirtualBox and is Linux only at the
moment anyway...
