The plan is to break out the NoRM specific functionality (LINQ, MongoConfiguration, etc.). As well as remove any functionality that has been superseded by the 10Gen driver (GridFS, for example) - although in removing the functionality, we may include compatibility extension methods. I haven't had much time to work on it lately, and there hasn't been a lot of interest from contributors in taking on the transition - as it will involve refactoring legacy code, rather than writing new code - it's not as "sexy." Any contributions could certainly expedite the transition and would be greatly appreciated..
