We know you can make a ship that uses drop tanks for jump fuel. So how about one where the jump fuel tankage *and power plant* are external? Fire up the power plant, run the fuel thru and disconect from the ship which then jumps. Put you in a bit of a bind if you get a misjump, but otherwise I don't see any major problems (assuming it is possible at all). Be useful for bulk cargo and possibly some military uses. Keeps some of the more expensive parts of the ship "at home" and usable for multiple ships. For two way traffic you'd need one at each end of the jump. Not sure what to call it. It's sort of an intermediate step between a normal ship and a jump gate. I think "jump tug" is already taken. Maybe jump catapult? -- Leonard Erickson (aka shadow) shadow at shadowgard dot com
