Has anyone any experience they would be willing to share around the issue of MM conflicting with CSLA (or other frameworks.)

- Has anyone moved from CSLA to MM or vice versa? And what were the reasons for doing so?
- Can MM and CSLA co-exist? Can objects built in one framework use objects from the other?
- Are there any collisions or conflicts or overlaps between the two?
- Has anyone found one framework better suited than the other for a particular job or application?
- Claims have been made in certain quarters that CSLA is better suited for N-Tier development - does anyone have experience with MM in an N-Tier architecture?

Any comments are greatly appreciated!
