From some quick reading it seems like the crewed Dream Chaser is intended to fly without a fairing. The cargo version's ability to fold the wings and fly within a fairing seems to be for 1) compliance with NASAs CRS-2 requirements, 2) wide compatibility with existing boosters that weren't designed for the forces that flying without a fairing would create.
Could be spin from Sierra but that's what they were saying to the press as of 2015 when they announced the cargo variant.
The problem with the wings is they generate lift during launch and that will screw up the rocket, thus the fairing. I thought there was no known solution for that.
It seems like you could mitigate that by designing the wing such that when mounted the angle of attack is 0 and thus no lift is generated. Obviously the wing would still have an effect when the booster changes orientation or in cases of high winds. I'm not remotely qualified to calculate the scale of those forces but I don't see why any of that would be a guaranteed showstopper given a booster with enough thrust vectoring capability.
