 All right, so that's the bottom line of this. This prohibition is coming down the pike. Contractors need to be getting ready for it. If you already have an 889 system in place, you're going to want to piggyback off of that for this. It's going to be a similar compliance regime, and you're just going to want to get ready. You've got a few years to do so, and you're going to be doing the same kind of due diligence that you're doing for 889. It seems to me it is narrower, like you said, that's on buying the stuff.
