Thanks guys,
I think I'll just mess with the daughter board when I have more time...the master board was my main focus, and it's good so far. As for the cabling, I'm an Audio-Video-Security installer, so cat5 is a natural fit for me. This is what I've got so far...so we'll just have to road-test the max limits.
