I've been going through this "thinking" process for a while as well. I
saw one of these ( http://www3.ns.sympatico.ca/abarb/routertext.htm ) a
couple of weeks ago and was quite impressed with the way DC is hooked
up. The box at the back of the fence slides over a dust port in the
table surface. The neat thing about this design is that there is no
cumbersome hose mounted directly to the fence! I've added this feature
to my plan.
