Interesting. "While there is high interest in identity federation, the technology is still in flux and will likely be more expensive and time-consuming to implement immediately rather than three years from now." The interest in a federation per se is shared mostly by content providers. However, web users have a very different interest - what I have called self-identification - and uptake here may be much more rapid than Gartner suispects, and in an idea world, will usurp identity federations entirely.
