It could be federated, basically the same API could be implemented or a common implementation can be used by a number of service providers...still not sure though what federation by itself adds to the core solution. I am the developer and have tried so far in vain to get the IRS to integrate. The IRS is the single largest data source for basic identity attributes in the US so integrating that would essentially allow almost every adult in the US to be able to leverage it. I have developed a Chrome extension to allow the use of IRS tax transcript information but obviously it is a very high bar considering the sensitivity of that information. ....still work in progress
