I guess I'm one of the younger members of this community, but don't let that fool you!
I have applied more of a vanilla implementation of FDD last year in my final year project at uni (16 developers), and recently just some aspects of it to my last J2EE project, which i worked on by myself reporting to two managers.
I have many views and still many questions on agile development. It's funny to me how so many IT professionals are looking "the next big thing" to fly straight into their laps, specifically I'm talking about those that view agile as being Fred Brooks'(sp) silver bullet for development.
