Refactoring in .NET

Brenton House is asking about refactoring tools for VS.NET. I've also used Eclipse in the past and it's refactoring tools are nice. I really miss them in VS.NET. Of the links he posted, Xtreme Simplicity looks pretty nice. I'll be following the comments on his post closely.

Is anyone working on an open-source refactoring add-in for VS.NET?
