I mentioned my idea for a diamond shaped inner barrel in another thread, so I thought I'd explain my idea a little further.
Be warned, Microsoft Paint sucks the big one...

Blue = BB
Red = Three point hop bucking
Black= Inner Barrel
The BB contacts the inner barrel at four points (2,4,8 and 10 o'clock).
In my head this MIGHT reduce the amount of bounce or vibration in the BB as it travels the length of the barrel. The three point bucking means you can adjust for backspin and left/right.
The gap below the BB should let gas/air pass underneath which would cause backspin (so very little hop would be needed).
I have no idea about the physics of airsoft or any knowledge of how such a barrel would be machined. I just thought I'd put my idea out there and see what comes of it.
