Christopher Kunz has posted this summary of his experiences (so far) at the PHP Vikinger conference for this year.

For about 4 hours now, the PHP Vikinger is in full swing. Everyone arrived between 10 and 11, and together we hacked up a makeshift agenda. Remember that this is an "unconference", so attendees are in full charge of the whole event. Our lead viking Zak, inspired by the mighty power of Thor himself, took it upon him to moderate the scheduling and get everything started. Now, everyone who wants gets up and does a presentation, starts a discussion or - as Kris is currently doing - stipulates brainstorming with the attending core developers and other PHP nerds.

He also mentions a discussion about what PHP's lacking and a talk from Ilia about PHP security issues. Sounds like things are going great so far!
