I think that what we should really do is have a notion of ScopeKey in the 
BeanMetaData[Factory] and the ControllerContext.
I've avoided adding it so far until we've sorted out the usecases for the
metadata, but it is definitely something that should be there.
If it is not specified, you would just use the deault rules from the
annotations or failing that ScopeKey.DEFAULT_SCOPE

I think we really need to discuss the use cases for how the metadata works.

I don't have a problem with you prototyping something so we have
something to "play with'. But the only way we are really going to workout
what the api should look like is by going through examples on 
how we expect this feature to be used.

I'll start a seperate thread on one example I was thinking about over the weekend.
