Both Stefan (in his blog) and Anne (on Facebook) have observed that Microsoft's definition of REST is: "An RPC protocol running over SOAP".
The document to which they both refer can be found at: http://www.globalfoundationservices.com/security/documents/WindowsAzureSecurityOverview1_0Aug2010.pdf The passage in question states: <<REST (representational state transfer) An RPC protocol running over SOAP used for many interactions within the Windows Azure Fabric and with Windows Azure customer development environments.>> As they say in exam papers: discuss!
