Implementing MemberSource for dynamic levels?

[markaddleman]

I want to implement a new MemberSource for a dynamic set of levels but it looks like the MemberSource interface wasn't really designed to be extended. Am I looking at the wrong thing?

I should describe why I need this: In my database, I have a column that contains a complex datatype which represents an arbitrarily complex hierarchy. I'd like to translate this hierarchy into a mondrian dimension.
