The paradigm reminds me of the message passing paradigm in "early days" object oriented programming languages such as Smalltalk. I guess remote procedure calling (RPC) and message brokers (COM and friends) is the 90s or 2000s version of distributing these messages (network transparency). How does Jolie relate to these concepts?

I just wonder, when looking at enterprise Java, whether there are not mature libraries which allow for distributed and high level application writing without changing the whole software ecosystem.
