title: Azure, Sync Framework and Access Control Service: Are there obvious shortcomings or problems in using this technologies together?
body: <p>I have a desktop application which uses flat files (some xml and small pictures) as data. I want this data to be available on other PCs which have the desktop application installed and usable by a smartphone client (WP7 at the moment) as well.</p>
  
  <p>The user should have it very easy to synchronize this data. He should be able to use accounts he already possesses (Live-Login, Googlemail, Facebook,...).</p>
  
  <p>I thought about using Azure Blob Storage to save the data in Azure, the <a href="http://msdn.microsoft.com/en-us/sync/bb736753" rel="nofollow">Sync Framework</a> to perform the actual synchronization and the <a href="http://msdn.microsoft.com/en-us/library/ee732536.aspx" rel="nofollow">Access Control Service</a> to handle authentication.</p>
  
  <p>I have not used any of this technologies before so any advice would be great but I'm searching foremost for errors or shortcomings in this strategy I don't see yet. Is this approach viable at all?</p>
