I think being able to define constraints as attributes in gschem as well 
as having a constraints editor that can be used from gschem and PCB 
would be the way to go. I'm not sure how the constraints editor would 
look though.. Dan pointed out the Specctra format, and the constraints 
editor should probably just be a front end for that.
