Mounting QS8 without back wall

I am looking for ideas. I have a home theater setup now and am getting ready to upgrade my speakers (I posted some question earlier). I love the QS8's but my home theater will be moving to a much bigger room (the 7000 cubic ft room I posted about in another thread). So here my dilemma: The rear wall is quite far from where people will sit and watch tv. People will sit say 15-18 ft from the tv (LCD tv), the wall is around 15ft behind them.
I am planning a 7.1 surround. Can the QS8's be effectively mounted on the back wall (seems kind of far)? If not any ideas on how a person would resolve such an issue. I am about to start remodeling, so I am looking for ideas that could possibly meet the WAF. I don't think the wife would accept the qs8's hanging from a hook.

You could use the QS8 stands.
Or mount them on the ceiling just above the back of the seating area.

To be a pain, I'll point out that you should avoid having your listeners at 15ft from the front and back walls. Land of the Null! But I would not worry about the Qs without a close reflective wall. Put them as directed on the sides of the listeners and the will perform as advertised. The question of rear-surround is more difficult.
Some in your situation have gone with direct radiating speakers on the back wall, others use Qs back there, but some say the benefit of the Q that far away is lost and the cheaper direct equivalent is enough. Others have done mid-room setups for the rear speaker where the rear wall is actually in another room and suspect their spouse and guests don't want to hear the helicopter at 105db as they cook!

I'd hang the rears from the ceiling using the Axiom full metal ceiling bracket. Unless that solution gives you wiring, aesthetic or cost problems. If that's the case, I'd do as Charles suggested and get some M2 or M3's for the wayback rear wall position instead. That might even make more sense depending upon how you're using the rest of the room - if you've got people spending time in that half of the room, you might like to have "all channel stereo" there rather than the diffuse sound of the QS series.

No; all channel stereo isn't an adequate substitute(for standard usage)for surround sound which sends different content to the surround speakers than is sent to the mains.
As to positioning the QSs or other back surrounds on the back wall(spread widely apart, a distance similar to the distance from the seats)that far back there shouldn't be a significant problem. Delay and level to compensate for the distance will be adjusted during calibration.

I think we were all in favor of using a direct firing speaker for the 6th and 7th channels, not to necessarily twin them for channels 1 and 2

Zimm is right, the center of the room is the worse place to sit, right in the null of a room. 38% from the front wall or back wall is ideal. My room is bigger than yours and I have my Q's hanging 7ft off the ground (bottom driver). The left surround is the only one with a wall behind it.
You could put the Q's on the back wall and adjust the distance, dB levels to compensate when calibrating.
