Is there anything Wine could do different that would help ReactOS development?[...] BV: You guys have certainly contributed a lot of your work back to Wine, including some of the utilities you've written. For instance, the task manager was recently ported from ReactOS. Do you guys have any plans in the works for developing more tools? Steven: I really want to see a solitaire clone make it in to Wine and ReactOS.[...] At some point we are going to have to develop replacement components for everything in Windows so if there is a program that Wine needs and ReactOS implements it then I will try to make sure it's released under a compatible license.”

In turn, that work required significant additions to Wine's shell32 DLL. In the past he's also contributed to Wine's Winefile application and various user interface things such as common controls.”
