The fourth day of the conference opened with a keynote by Eric P Allman, author of a little MTA some people may have heard of called Sendmail - an "... old program that has changed the world."

The second day of Linux.conf.au in Brisbane, Australia, opened with keynote speaker Vinton Cerf, vice president of Google. Vint Cerf is often spoken of as one of the 'fathers of the internet', having been one of the co-designers of the tcp/ip protocol.
