The conference is hosted by Chimera, a research group that spun off from BT a few years ago. They are now associated with the University of Essex, and the combined academic/consulting research they do gives them an interesting perspective.
I went to PII 3 a couple of years ago, and it was a great experience--one of those few conferences where every talk was worth listening to. Even if you can't attend the conference, I recommend checking the website from time to time as it is updated with the abstracts and presentations. Most of the PII 3 presentations are available online as well.
