agree, and this would be the general idea.
though once you start changing entities in the uicommon, it's kind of 
infecting.
i suggest to start with a simple one (say, bookmark, then config, then 
tag, etc.).

you will then find some queries don't return business entities though, 
rather more complex types.
so you could also start by mapping all the quries not returning a simple 
list of entities.
