After installed a tunnel between my FreeADSL connection and the freenet6 ipv6 network, I was not very happy with the latencity of this tunnel.

In reading more about IPV6 and tunnel brokers, I get an excellent advice about the best choice of tunnel broker by area on the gentoo website: http://www.gentoo.org/doc/en/ipv6.xml.
