Dryad is not MapReduce. M/R is just a very simple case of what Dryad can do. But Dryad is not available for serious use outside Microsoft. Also Google only got implementation patent, it's only applicable to Hadoop, which is a Java-based clean room implementation of Google's M/R.

That's irrelevant ... if it touches on the claims of the Map-Reduce patent, then it infringes.

Being a company that releases stuff in the open sure is a disadvantage.
