This looks very interesting - unison is a great tool. I rember fighting to get plan9 networking working with qemu/kvm and Linux, and never quite figuring out how to connect the dots. On paper it appears 9p should be a perfect fit for the use-case. (However, I just found [1] - maybe I'll give it another shot). But it seems kind of obvious that the functionality needed to get this stuff to work, is an entire network filesystem stack. It seems the obvious choices would be to build into VirtualBox either nfs, or webdav - or leverage host/external support for nfs, cifs, or something like OpenAFS. With sshfs as another pragmatic option. Maybe in the future ipfs will be a viable option too. But I think cifs is still the "mostly works, with/without complex auth, cross platform" - with webdav a distant second.
