This may be just dumb, but I am looking into getting a Wii and wondering if it would work for me. My AV stuff is setup in an enclosed closet about 10' from where the TV hangs on the wall. I use a BT keyboard and an RF universal remote to control everything. Would the Wii controller work (BT?) without anything like a bar under the TV (not an option)? If not, are there any 3rd party controllers which would work without a line-of-sight, either through BT or RF? Thanks!
