Hi Brian,

You probably caught everybody on an off day. Majority of the companies are
closed today. I saw the sketch drawn on the overhead briefly because during
that time I was in another room. I could also provide a diagram giving the
high level architecture. However, Margarete gets the first call as she has
already worked on it.

We as a team have to work on this in all earnest from April 5th. Let me
start with the name for the document. How if we call it as "LMDS system
architecture"
