From a recent posting on DZERO news by John Womersly:

 

A 2 week linear collider workshop is being planned next summer in Snowmass, hosted by the ALCPG, August 13-27.  The idea is to sharpen the physics case for the ILC, do serious detector design work, and move the machine along.  This focused meeting is intended to help the international community become more unified and coherent now that the technology choice is made.  The organizers hope for a large turnout and a "working" workshop environment, and ask that you put the dates on your calendar.
