cf.Objective() 2011 has come and gone, and by all accounts it was an awesome conference. I presented an Introduction to Browser Automation and Testing with Selenium, and I'm making my slides available via this blog post. You can download the PDF here.
The real meat of the session consisted of demos of Selenium-IDE, Selenium-RC and CFSelenium, so I'm not sure that you'll get much from the slides alone. If you're interested in using Selenium via ColdFusion, please visit the CFSelenium project and look over the readme file. It should give you all you need to get started writing your own functional tests with ColdFusion and Selenium.
