Good news, everyone! I have created the missing whiteboard diagram that 
we all needed at the design summit:


I've documented 5 possibilities. (1) is the current implementation, 
which we agree we want to get away from. I strongly favour (2) for the 
reasons listed. I don't think (3) has many friends. (4) seems to be 
popular despite the obvious availability problem and doubts that it is 
even feasible. Finally, I can save us all some time by simply stating 
that I will -2 on sight any attempt to implement (5).

When we're discussing this, please mention explicitly the number of the 
model you are talking about at any given time.

If you have a suggestion for a different model, make your own diagram! 
jk, you can sketch it or something for me and I'll see if I can add it.
