Microsoft seems to be making a lot of deals lately centered around playing nice with others. To me, this indicates that Microsoft has truely embraced the service oriented world. Assuming SOA takes off as planned and interop difficulties are significantly reduced, deals like this won't be suprising in the future, they will be expected.
