As I pointed out in an earlier post about a new Mode A bird, we aren't necessarily limited to a *single* four inch cube.  The launcher we saw at Bangor could handle a payload three cubes high.  Link two three-cube packages together and you have a significant chunk of hardware with lots more surface area to support a much better power budget.  To use a tired phrase, we have to start thinking "outside the box" when it comes to uSats and start thinking of a single 4x4x4 cube as a *building block* not the final form-factor.
