Davey Shafik has already gotten some of his experiences down in blog post form from the php|tek conference today, actually starting with the day previous in his Day 0 and Day 1 posts.
In the Day 0 post he just mentions arriving at the conference and getting things ready, but Day 1 sees him giving his "Future Deployment of PHP Applications" talk and his upcoming "Migration to PHP 5.1".
He also mentions videoing the presentation from today ("Deployment" talk) and is hoping to get a Flash video of the presentation up for all to see post-conference (a great idea for non-attendees).
