That said, I do have one concern: once this ship reaches its destination, how do we get it back? An Oberth flying back from the new Kadeshi homeworld is very likely to suffer some kind of fatal mishap along the way, I would think. A larger, stronger ship would be better able to take care of itself.
I'm not sure we do get it back. A larger, stronger ship... would still be at an unacceptable level of risk for a trip of "many thousands of light years" left alone and unsupported.
Eh, maybe this whole thing isn't such a great idea. It all sounds very exciting, and then the more you think it through the worse an idea it sounds like. I'll have to see what options are actually presented for us to vote on.
