How to use grease pencil for architectural visualization?

There are a lot of tools in Blender that help us to create architectural visualization, but some of them may add another layer of productivity, even for schools that teach architecture. In the last releases of Blender 2.4x a tool called grease pencil was added to allow animators to create notes and sketch over a character, making it possible to work and share notes on a team. But, a tool like grease pencil can be useful to architectural visualization artists too, and help on the process of developing details for a scene.

Since I also work as a teacher and evaluating projects from students all the time, using grease pencil is quite important for me, in order to keep a clear communication with students, about the problems and development of their projects.

If you never thought about grease pencil as a tool for architectural visualization, I just found two great tutorials about grease pencil, showing how to use them in an architectural visualization context. The videos are not new, in fact they still use Blender 2.5 Alpha 0, but this doesn’t mean that they won`t be useful.
