Based on my son's behavior today, you will be able to do this in a few hours.

With the extends/bases behavior I am planning to add, you will be able to do 
exactly this.

I think that with a little bit more code for the KGS and considering all the 
other possibilities, such as find-links and versions, we have enough 
flexibility. I think the challenge will be to come up with a recommended way 
to do all these things. Maybe we should collect our use cases again and see 
how they can be solved.
