Since I was privileged enough to work with Steven Woodward in January I have thought about many of the things he taught me, but nothing as much as his Eighth Law of Identity - "There must be something in it for everyone".

I've been trying to work out why there isn't much momentum in the CardSpace world - when compared to the WPF's, the WCF's and WF's of .Net 3.0.

I wonder what is missing, and the only thing I can come up with is that the success of CardSpace, and in turn the Identity Metasystem, relies on sales of Vista.

However, I find this to be a bit of a "Chicken and Egg" problem - why would people move to Vista (or install the .Net Framework 3.0 on XP) if web sites are not implementing CardSpace? Why would web sites invest in enhancing their systems when the potential user base is so small?

I think that out of the .Net 3.0 technologies, CardSpace will have the most important impact on the Internet landscape.

I guess it is just a matter of time - one day everyone will have a bunch of Information Cards that move around with them, giving them secured access to all the information they like.
