Good DDD samples
I'm learning about DDD and enjoying every minute of it. However, there are some practical issues that are confusing to me that I think seeing some good samples might clear up.

So being at peace with those issues, does anyone know of some good working code samples that do a good job of modeling basic DDD concepts?

Particularly interested in

 - An illustrative Domain Model
 - Repositories
 - Use of Domain/Application Services
 - Value Objects
 - Aggregate Roots

I know I'm probably asking for too much, but anything close will help.
