I think this would go too deep into the ORMapping issue, which I would like 
to punt for now. However, I agree with your point on having a common 
interface for all sorts of external data sources.

Can you provide links to documentation to the named technologies, such as 
"disconnected, multitable relational dataset"?

I agree, but then I think this should be a layer on top of the low-level 
communication framework.
