You should see the mess of wires I have in my loft. TV, antenna (as backup), DVR, DVD player, DVD burner, BD player, two full 5.1 speaker systems, a cable modem, two routers*, desktop computer, UPS, and printer -- that all on one 8 foot wide wall. Then layer on top of that wiring to feed Internet to two laptop computers on the opposite wall. Yipes! Everything starts out nice, but as soon as you have to change something, it all becomes a big mess! We try to keep it as neat as we can, but that much wiring, shoved behind a television stand, is just going to be a jumble no matter what.
I do have plastic cord chases for some of the longer runs of speaker wire and Ethernet cords, as they go around the side of the room to the opposite wall. That keeps things looking a bit neater. It doesn't sound like running wires around a room is your issue though.
* In this day and age, putting only four ports in a router is ridiculous, even for a home router: Besides the three computers (the desktop computer is an old clunker we use to backup the two laptops on to), the printer wants to be plugged into the home network, as does the DVR (to get its program information) and the BD player (to feed it Blu-ray Live content). So that's six devices that need to be connected. Even with two routers, we're "full up" (because the routers need to be connected to each other, so that takes up one port on each of them).
