With all the games coming out for the iphone & touch, and comparisons being made to Nitendo DS and Sony PSP, is there any technical reason why there could not be a slider type accessory that would add the missing game controls? Seems that someone could come out with a slider with buttons for firing/control on the right, joystick/cursor control cross on the left, with iphone or touch in a horizontal position. iphone placed into the adapter, with connections through dock connector, maybe even with a supplemental battery as part of the pack?
