Not only does Whobar support InfoCards and related identity technology, but check this out:
Whobar makes it easy for users to register and login to a website using their choice of emerging identity protocols such as InfoCard, i-names, and OpenID. It enables developers to easily add support of all these emerging Identity 2.0 technologies to their site. The benefits of this for users is a common website login experience. For web developers, to streamline their user registration and login process so that they donâ€™t need to store user passwords, nor users needing to remember yet another password, thereby improving site conversion ratios. Future releases will also allow users if they so choose, release data about themselves with a single click.
Given the interest shown at the recent DIDW and Future of Web Apps conferences from Phil Windley, Rafe Needleman, and others in the community, weâ€™ve made the Whobar technology available as open source. Whobar is written in PHP, but works like a proxy, so that the web application can be in any language. However, weâ€™ve also been contacted by several developers interested in contributing a port to C#/.NET so stay tuned for additional modules. If youâ€™re interested in getting involved, please check out our contributing page.
Congratulations to the SXIP team. When I saw this at the DIDW conference I thought it was amazing. I'll do a video capture over the next few days so those who haven't downloaded Cardspace or a Chuck Mortimer / Ian Brown identity selector can see what it's all about.
