We also have a Silverlight/WCF application with NHibernate. However, we've adopted the Unit of Work pattern and modeled it after Jimmy Nilsson's workspace concept.
Our WCF service is a thin facade in front of our application services. The application services are responsible for: 1. Orchestrating between domain services and domain aggregate roots 2. Converting between DTOs we use through WCF and domain value objects 3. Defining the unit of work Thus, our domain services and repositories expect their to already be a unit of work (which in our case wraps an NHibernate session). The domain is ont responsible for opening nor closing it but just expects it to be already set up. It is our application layer that manages the unit of work boundary (a.k.a. NHibernate session management). This has been working quite well!
