Re: starship-design: scoops and sails and something to push against.

perhaps we could just mandate a drive with given parameters, and 
content ourselves with design of the ship and living quarters, 
life support etc.

perhaps we could do that for several different drive types (FTL 
vs multi-generational vs near relativistic.

that way, if any of the breakthruoghs happen, we will have the 
start of a design.
