The Americans have been using these for years. They are called the homeless management information systems. There's off-the-shelf technology; it's actually pretty straightforward. But it's a question of how you engage all of the different funders, all of the different agencies in building a standard system.
To me, frankly, the key to ending homelessness is having a coordinated homelessness system of care. It means having a homeless management information system that is the IT infrastructure of that whole system; a system that can track people coming in, understand who they are and what they need, understand what happens to them in the system, and show what happens as they move successfully to permanent housing; a system that can track the performance of those programs—we can't really do that today—and do performance management quality assurance with the programs in the system.
