Ok, agreed.

I think that text was originally written by Brian, but I always read it 
as "transport level solutions". However, I think that adding additional 
work like what you describe above might be something for later. Still 
it should be done, and I think that was one of the things we discussed 
in D.C (brought up by Jim Bound and later channelled by Brian). Not 
sure that we want to include it from the start though?
