"Microsoft's DLR is a layer on top of their Common Language Runtime

"Novell will be requiring copyright assignments or contributions to be

I imagine the OpenMoko embedded system is a special case.

It is not needed though it is used if available. They got help from
their Xgl+Compiz+Glitz guy David Reveman.
Here is Miguel de Icaza describing the development decisions some more...
"The other consideration to move away from C# to C at the time had to
do with the early conversations with David Reveman who wanted to
hardware accelerate this. The idea was to turn the Silverlight
high-level operations into a scene description that we could transfer
from the client applications directly onto the compositing manager (On
modern X installations this is what actually puts the bits on the
screen and what has enabled all those spicy effects like the rotating
The idea here is that the Silverlight client could detect if it was
running under a compositing manager that offered rendering on the
server and it would off-load all the rendering to the layer that can
talk directly to the OpenGL hardware. "
FYI I am just a lowly Mono consumer (if you are generous you could
say QA) I am neither associated with Mono or Novell directly so it is
always better to check with the actual source.
