Brian,
When I look at my room, that looks like a huge amount of work, and probably near 60 feet of cable. There is one wall, a door, another short wall, a 4' x 8' nook, and then another long wall -- that's a lot of baseboard to pull, not to mention that two of those walls have hot water heat exchangers along them. Man, I'm just sweating thinking about it.
Maybe I'll call one of the local net cabling companies to see if they can go under the floor -- again, complicated by a double sheetrock ceiling in the basement, and dry, blown celluose insulation (poke a hole in the ceiling and it rains confetti all over you.) But, it's only 14 feet across, so they may be able to do it with a fish tape. Going up and over is even worse, because there the blown celluose insulation was blown in in a wet matrix material that hardens (so you don't get the confetti problem when you poke a hole in it.).
And, I really don't want to run wireless -- for a variety of reasons.
Thanks for the advice though,
Jim
