Hi Adam,

   Stuart Henderson will be organizing a study of a  large circumference e+e- 
machine within the APC.  The resources to study the physics and detectors 
of such a machine within Fermilab are minimal.  I think that we can build on 
many of the existing ILC studies.  Rob Roser has volunteered to help gather 
existing references.

This kind of options are likely to surface at Snowmass and more work is done in a coherent fashion - more useful the discussions at Snowmass will be.
