Silverlight 4 Trusted Application - Can I drag widgets outside the window?

I have a feeling this really isn't possible, but (for example) would it be possible开发者_JAVA技巧 to implement a trusted Silverlight 4 filesystem browser that allows me to drag files from within the Silverlight application to another application on my desktop?

For Windows... technically, maybe being able to run your own app when a drag is going outside the area of the app. But super complex and challenging.

You would need a few things:

• Elevated SL4 OOB app
• A COM component on the system, or a native code app embedded in the app that you can execute with parameters about a drag operation, look into isolated storage, etc.

You monitor when a drag starts, and then would need to execute your native code app somehow to realize the drag. Even then, I don't think the new app could pick up on the true drag operation.
