Roslyn and Mono

As an innocent bystander, my biggest concern is what's going to happen to nrefactory and friends. Omnisharp[1] currently relies on these and mono to provide intellisense and refactoring to editors not monodevelop.
Will they have to put on an equal amount of effort into putting to Roslyn if they want to remain on a maintained codebase?
So don't worry about OmniSharp too much :)

I'm currently working on Roslyn CoreCLR and cross-plat and Mono is working on integrating more of Roslyn into their stuff, but I don't think the two are necessarily connected, so I wouldn't strictly describe the two as duals.
Note: Only works on Windows right now, going to get to Linux/Mac ASAP :)
