In commemoration of the opening of the Clannad movie on September the 15:th, the Air Movie will be released for free streaming in three consecuative parts from Animate.tv (JP). It requires a newer version of Microsoft Internet Explorer and Microsoft Windows Media Player with digital rights management to be able to run though. For more details (in japanese) see this page and for those who want to try out to see if things work, here are some links to samples of the different parts.
