Hi,
the client does not know about OR at all. There is NO WAY to lazy load
something. The client only know objects.
In a real good client architecture a view/control works against a
model proxy in the client (sometimes I call them client object cache)
Either the model object is already in the cache or it will be
requested.
In such an architecture the use of comet/server-push techniques is
essential.
You could decide on server side which strategy regarding a certain
model object is the best ("eager" supplying dependent object too, or
not )
However, feeling well in the async world is a prerequisite
