Some time ago I was trying to solve the same problem. I didn't
implement it but in my toughts, only :-), I came up with something
involving object annotation plus adapters to extend the interface
schema and modify existing objects to fulfill the new interface
schema. IOW, store extra fields in the object's annotation.
Of course I would need to do a lot of UI magic to push those extra
fields into the object and some other controls to specify ordering

This is something that I would like to do some time. If it works it
would be really cool.
