Progress on Peanuts?

It looks like there might be progress in helping treat/prevent/even eliminate peanut allergies, as described in the NYTimes today. Because the kiddos had numerous food sensitivities, we have--at the suggestion of our ped--tried nuts yet, though I'm convinced they've already ingested peanut dust or oil in any number of processed foods without effect. I'm afraid, though, that by the time they can eat peanuts they won't want to. They know they can't have them and don't even try. I'm not sure they'll try when they can, after years of avoidance. But we'll see.
