You're going to have to get in touch with Nathan.
You didn't by any chance buy a seat to next week's Advanced training in D.C, did you? He's going to be talking there on this exact subject.. ;-)
Well, I don't think I can make it to that training, but i wud be highly obliged if u can provide links to online documentation on this subject.....especially, on the theory / principles beneath the implementation.
Thanks in anticipation,
Sorry, you still need to get in touch with Nathan with regards to that. He is the master, not me ;-)
