Interesting if not a little over hyped. I'm not sure three of four implementations on top of it could be termed "a Rich Ecosystem". But certainly a step in the right - concurrent - direction. While it appears to be able to span machine and clusters does anyone know if it can span cores within a machine or do I need a concurrent language to achieve that?

A few people have pointed me to a map/reduce like research project microsoft is working on called Dryad. Dryad is an infrastructure which allows a programmer to use the resources of a computer cluster or a data center for running data-parallel programs. A Dryad programmer can use thousands of machines, each of them with multiple processors or cores, without knowing anything about concurrent programming.
