Hey, news about .NET Services November CTP are available at the team’s blog. They have outlined the launch functionality available @PDC in 2 weeks time:
Access Control Service Feature-Complete Capabilities
The Access Control Service provides an easy way to control access to REST web services and Service Bus communications while integrating with standards-based identity providers, including enterprise directories and web identity systems such as Windows Live ID. Authorization decisions can be pulled out of the application and put into a set of declarative rules hosted in Windows Azure that can transform incoming security claims into developer-defined claims that web services can consume directly.
Service Bus Feature-Complete Capabilities
The Service Bus makes it easy to connect applications together over the Internet. Services that register on the Service Bus can easily be discovered and accessed, across any network topology. The Service Bus provides the familiar Enterprise Service Bus application pattern, while helping to solve some of the hard issues that arise when implementing this pattern across network, security, and organizational boundaries, at Internet-scale.
Latest SDK is available as download on the Azure site.
