I serve the binpkg host from my desktop to my LAN with nginx but I'm considering git from the booted container. I also mount $PORTDIR via NFS to have the same tree( bandwidth is expensive for me, and I also don't want to have tons of portage tree's around as I use the same method for another amd64 pc with an older processor, that has only 2 threads)
PD: The next step is to make the upgrades be handled by ansible but I haven't sat down to make it happen.
