one suggestion... hire an electrician (or whatever) to run some wires to your other rooms. if you get tricky, you could have a cat-5 wall panel in each room. while you are at it, have him/her wire the place for 1Gbps instead of 100Mbps.. might as well. if it were me, i'd have one near the TVs (tivo ftw) and a drop in each bedroom. couldn't hurt to price it out (i'm guessing a couple hundred $$)

it'd also make the place look neater (at least less network cables)

just my $0.02 worth
