  I've not worked with many commercial fab shops, so my comments may be 
a bit simplistic.  But since different shops have different 
capabilities and requirements, it might be useful to have some sort of 
a "design rule dialog box" into which one would enter things like the 
minimum line width, clearance, allowable drill sizes...and solder mask 
relief, which could then be applied on-the-fly to elements with a bit 
of coding.  And perhaps a text box into which one would enter the name 
of the fab house those rules are for, then all of that could be stored 
in the layout file.

  Thoughts?
