Yes, so again, at the wholesale level, I think that's well covered and quite available, and I think you can get at it, but in fairness, as Greg said, you have to kind of piece it together, in terms of its being centralized and brought together. I think you could go to the various exchanges, clearing houses, other aggregators, brokers. There are just a lot of third party entities that have this information, so you'd have to cobble that together, I think.
In terms of actual end-user information, yes, other than these regulated rates stuff, I'm not sure there's the same level of transparency on that front.
