Side Note from NHibernate
Since version 1.2.0 NHibernate allow us to maps SQL Stored Procedure and Functions. But still a lot of limitation there, one that i really hate it is lack of support of Association and Collections. So i will be happy if the LINQ NHibernate is really fully support about that. Ayende has publish the LINQ NHibernate in NHibernate Contrib, i will see that ASAP.
