Future stable depend of net-firewall/firewalld, which will be a depend of app-emulation/libvirt. I really only need amd64 and x86 but you guys can get whatever else you'd like.
When do you plan on stabilizing firewalld? If it's not within a week or two, I would suggest stabilizing python-slip-0.2.21. [By the way, I played around with firwalld-0.2.5 in July, and came away with the impression that it's unusable, unfinished, and not suitable for ~arch in the main portage tree, much less for stabilization. Has this really changed so soon?]
