@Joost De Valk - That is great news. Just subscribed to it and am looking forward to hearing the first half of the interview with Frederick.

@Frederick Townes - Thanks for the compliments on the question. By the way, I wanted to say thank you and commend you for contributing back to the WordPress community through your W3 Total Cache plugin. Will be interesting to see how it scores amongst all the other plugins in the competition. Seeing large sites that are powered by WordPress give back in this way is the exception rather than the rule.
