Microsoft and Open Source

It's very interesting to note the Microsoft's involvment in the Open Source (or open source) arena.
I came across this presentation held by Sam Ramji - director of the Open Source Lab at Microsoft - at the latest EclipseCon. It shows how Microsoft and Eclipse Foundation are working together on making Higgins and CardSpace interoperable and on building SWT on top of WPF (to let Eclipse shine on Vista).

One thought coming on my mind: how long is it going to take to have Visual Studio as an Eclipse plug-in.
