The issue is (I think) that the ExpressPCB software can only be used to 
create files to order boards from them - or can it now export ordinary 
gerbers?  (Otherwise, to go with another fab. I presumably would 
re-enter the schematic, and re-route it - granted not all *that* hard, 
but still a day's work.
