How does PEAK's peak.model package compare/contrast with the Naked 
Objects approach?

It seems the automatic UI is the primary difference, but I wasn't sure 
if there was a deaper conceptual difference that was already known.


ps - Naked Object (http://www.nakedobjects.org) is at the least 
interesting but I'm not sure the generated UI would satisfy many customers.
