DataObjects.Net vs NHibernate: conceptual differences and feature-based comparison

I written the document that might help the people choosing among DataObjects.Net and NHibernate to make a decision. Currently its second part related to feature-based comparison (feature matrix) is actually a preliminary one (that's explained in the document), so later I'll rewrite it. But anyway, I hope this will be helpful.

As usual, any comments and suggestions are welcome.
