Yes, we've moved beyond that thought.  Would you like to clean it up  
or should I?

I think this is currently the biggest bone of contention.  I'm going  
to repost your statement so that we can open it up for discussion.   
Then we should take a email poll on the subject.

Steve, Jeff has been yanking my chain to start writing.  You mentioned  
that you would like to help.  Perhaps we could have a phone call when  
Jeff gets back to discuss how it all should go.
