Indigo in LongHorn

Longhorn Developer Center: Code Name Indigo: A Guide to Developing and Running Connected Systems with Indigo: "One of the key benefits of Indigo is that it provides a unified programming model and protocol stack for all common language runtime (CLR)-based remoting technologies. Indigo marries the best of .NET Remoting, ASMX, System.Messaging, and .NET Enterprise Services into a single framework, allowing developers to freely combine features such as declarative transactions, pluggable interceptors and transports, and XML Schema-based serialization."
