I've got a new article in the latest edition of the DIWUG, the Dutch Information Worker User Group. This is a great resource with a very diverse mix of articles for all disciplines for those in SharePoint. The latest edition contains articles by Spence Harbar, Wictor Wilen and many others.
In this edition I tackled integrating SharePoint Online 2010 & Windows Azure & addressed some of the authentication challenges you might run into. Check it out!
