large-object-pattern

I have a conceptual model in EDM where one of the entities has a property which is essentially a big value object whose properties aren't really useful as columns in the datamodel. I'd like to apply the Serialized LOB pattern to it so that I can fit it into a 192 byte binary column.

How do I map this in the EDM v4? Is it even possible at this time?

Actually, is it possible in any ORM?
