"So," says Mark, "to start with, I think I'm going to claim a three-month lead time on a clone order. Short enough to hopelessly outmatch the competition, long enough to be vaguely plausible as something other than magic and to give me time to find you and drag you back here to fulfill unexpected orders if you're somewhere else when I get one. I will demand tissue samples or accurate gene sequences from customers, and we'd better actually use the provided material as the basis for growing the new body, even if you can do it another way. We should probably also whip up a convincing-looking medical lab somewhere on this ship, even though I fully intend never to let anyone access it. If someone does break in, and doesn't find any evidence of clone-growing facilities, we'll be facing some uncomfortable questions."
