Interoperability is actually what I just talked about. The veteran actually has the ability, if we put all of their lab results onto their My HealtheVet Internet site, to decide to send it to their Google health record or their Microsoft record and then share it with private sector physicians. It's partially that, and it's partially our participation in the nationwide health information network, under the auspices of Health and Human Services within the U.S. government. It's building a foundation for all health care providers to connect to this nationwide health information network, much like the U.K. Spine records service or some of the work you're doing, so that we can exchange information. All of that requires the veteran's consent and authorization to exchange that information.
So what we're doing with the Department of Defense is interoperability. We'd like to expand that out for the patient to control it and to exchange more routinely with the private sector.
