As previously announced (https://spaces.at.internet2.edu/x/3QA6AQ), we have installed a redirect from the InCommon WAYF to the InCommon Discovery Service. This redirect will remain in effect until July 6, 2011, at which time it will be removed. At that point, HTTP requests for WAYF services will fail, so if you haven't updated your software to point to the new Discovery Service, please do so as soon as possible.
Now that the venerable WAYF has been retired, we will focus our attention on the user interface of the Discovery Service. A number of bug reports and feature requests are outstanding, most notably a request for an incremental search interface. The current implementation (SWITCHwayf) does not support incremental search, so we will switch to a new platform that supports incremental search in a subsequent release.
For example, the Shibboleth Centralized Discovery Service supports incremental search, but since this is a new platform for us, we would need to deploy, test, and replicate the Shib CDS on our infrastructure. You can help by trying out this incremental search feature, and, if necessary, sending your comments to the participant list. Once we've received your comments, a refined testing and deployment schedule will be announced. For initial testing, an "out of the box" test instance of the Shib CDS is at http://bit.ly/f3y0uD.
