I finally made a script based on the dimensions in ladyadas shield and also used her jumper pads. Its actually pretty easy to do and has made me realize how powerful eagle is. The shield schematic has the four jumpers for all the pins. You then connect your stuff to the pins, generate a board and then run the script which creates the correct board outline and positions for all the jumpers. Makes it very fast to generate a custom board. I can upload it to the community, however it isn't production proven yet.
