Good questions.

The room of interest has a finished bedroom above it, with no cat-5,  
and a finished basement room below it, with no cat-5. I can get cat-5  
in the attic, but that's two floors up, and I reckon it would be  
pretty easy to drop cable into the upstairs room, but then getting it  
down another floor would be tricky, since there's a sub-floor, right?

The odd thing is that I'm sure there *used* to be cat-5 in the room of  
interest, but I think it got removed when the previous owners knocked  
out a wall in the room to make another door.
