[Mono-dev] Managed DirectX

This is available in Managed DirectX indirectly through the Surface.GetGraphics() method.

I think I don't understand what you're looking for. Managed DirectX is a thin wrapper around the DX9 COM interfaces. The most important entry points are functions like Direct3DCreate9() and DirectSoundCreate8() (ignoring for the moment all the D3DX stuff)-- everything else is available through interface calls and calls to IUnknown functions. To look at it another way, if you have an implementation of COM and DirectX 9, all you have to do is wrap it; the exact same managed DLL should run on both Windows and Wine. 

(I confess to ignorance about how Wine works, so if that doesn't sound right, let me know.)

It sounds like what you want is an implementation of Managed DirectX that doesn't actually use DirectX, or at least talks to the Wine libs more directly. Is that right?
