Continuous Integration for PHP

If people are interested I could give a presentation on Continuous Integration for PHP. Covered topics could include:
What is Continuous Integration?
CI tools (CruiseControl, Jenkins, Bamboo)
Unit testing (& TDD) with PHPUnit
User Acceptance Testing (& BDD) with Selenium (using Facebook's PHP Web Driver)
If I can find a good web page to demo I can include a Selenium demo as well.
