Most of us are probably aware of Singularity, a research operating system out of Microsoft Research which explored a number of new ideas, which is available as open source software. Singularity isn't the only research OS out of Microsoft; they recently released the first snapshot of a new operating system, called Barrelfish. It introduces the concept of the multikernel, which treats a multicore system as a network of independent cores, using ideas from distributed systems.

The difference of the license-side between Singularity and Barrelfish is, that Singularity is open source
http://www.codeplex.com/singularity/license
but Barrelfish is OpenSource (like the OSI-definition, or free software like the FSF-definition):

From the technical point of view, it both OperatingSystems are very different and can not be compared to each other.
But from the license side, Barrelfish is a lot better! :-)
