I just uploaded the final Azure Edition as well as a combined Azure and on-premise source package to Codeplex.

http://identityserver.codeplex.com/releases

I am also in the process of building a wiki for documentation – it is not done yet – but can be browsed here:

http://wiki.thinktecture.com/IdentityServer.MainPage.ashx

Any feedback, bug reports, volunteers (coding, setup, wiki) – please DM me.

Have fun!
