I have to appreciate the Brazilian effort for promoting IPv6. I attended a talk on a university about 5 years ago where members of the Brazilian Internet Steering Committee (CGI.br) talked about IPv6 and why it's the future. It was very informative, and I also found out they offer free courses about IPv6 networking, with certificates included. I think CZ.NIC offers something similar, but they should be promoted more often so sysadmins can prepare themselves for the eventual shutdown of public IPv4 addresses.
