John,

Another thought on packages under PCB. PCB only allows rotations of 
packages in increments of 90 degrees. Some designs require packages to 
be at a different rotation for example at 45 degrees. This limitation in 
PCB can be over come by creating a package with the offset in rotation 
that you desire. So I would request that you add this into your auto 
package generator.

Yet another issue is specific to flex circuits. Flex circuits are 
literaly glued together. The copper pads are glued to the flex material 
and can easily be pulled off. Flex circuits overcome this by making 
masks that cover parts of the pads or pads that go partly under the 
masks. Flex ciruits can also use wierd shaped pads, such as pads with 
tabs that go under the mask layer to achieve that hold down.
