peering charges?

Curious thing, the CEO of my company called me the other day and was worried about who we were peering with. It seems someone put a bug in his ear that the larger providers were about to start charging some of the smaller providers for bilateral peering. I haven't heard anything about that at all... so either a) the ceo is mistaken b) I've missed some important annoucement recently either is possible. Has anyone else heard anything about this? Thanks, davec
