In the meantime, most of our attention has been focused on release 1.1. This release will enable many extension points and plugins that will be used to build out the rest of the Nexus functionality. There will be two milestone releases, 1.1M1 is staged and should be out within a few days. M1 brings with it an extensible realm implementation that will make it trivial to insert new realms for authentication/authorization against systems like LDAP or AD.
