The most obvious and arguably the single biggest advantage of an IdF is to allow the creators of services to deploy them without having to worry about the overhead of maintaining a database of users. Examples of services are: library services, grid applications, video conferencing, cloud services, commercial services and certificate services.

Over and above this, IdF can potentially improve the end-user experience by deploying functions such as single sign-on, where, within a single web session, the user will have access to multiple services, without having to log on separately. You attend a conference on the campus of another participating organisation and with a single, universal log-on access their indigenous Wi-Fi service and have the same experience as if you were at your own home network.
