Personally, I won't settle for anything but wired speakers, regardless of how difficult or time consuming it is to run the wire. A wall is easy to plaster and paint. If you paint the entire wall you don't have to worry about matching a spot or strip. If the paint on the walls is more than a year old you probably will not be able to properly match a spot or strip, even if you use paint from the same original lot/gallon. A smooth ceiling is equally easy. A stippled/popcorn (sprayed plaster) ceiling isn't, so it's preferable to keep holes to originally smooth surfaces.
