I think you would do well to setup a squid proxy and block outbound traffic for the affected machines. We've had great success with squid in our environment. This gives you a tremendous amount of flexibility on your access control, and it means you don't have to be concerned about which transport methods are used when updating/installing. Added bonus is that the squid caches your Gentoo download objects. -- Matt
