 winner-take-all type of a vendor approach or some kind of open standard interoperability. And the industry for a lot of these things isn't to the point where there is a commoditized industry standard solution for things. And because of where we're at in that arc of maturity, we're not going to be there for quite some time. So we're going to be making these vendor decisions and then having to figure out interoperability and kind of cross-pollination later. And it's a huge challenge because it requires such intimacy with the products you pick.
