Subject: Black Peals Interface to Titan

Attached is a draft of the strawman for the Titan Black Pearls Interface in
visio (this one really has lables that you can see) and a very rough cut of the
fields Settlements is interested in. In addition, I thought we could use an
issues document, so I drafted one up. Thanks Gloriann
