Lucky after all

I had already got over the disappointment of not getting a speaking slot at Lotusphere. But judging by this thread over at the Turtle's site it appears that even if you did get approved you still have to pay for your ticket. Surely that can't be right? If it is then what benefits do speakers get (other than the kudos and CV fodder) for all of the effort which goes into preparing their presentations?
