The slides that I sent out jan 16 include the updates from the breakout
session that I chaired.
If useful, i can take that and turn it into text.

also, to dan, i suggest that the presentation that jeff gave link to the
updated presentation that I sent.
what i sent is just an update to the presentation jeff gave from our group.
