That's fine.
The thing is, though, when you look at taxation or at health, if I have to prove something, I might have to acquire information from different levels of government.
How do you get the interoperability?
It's not just one level of government. You can start off at the federal government level, but eventually, if this is going to work, you should have access to all the information that's reposed, deposited or held through the different levels of government.
