Scotty: Here you go. You set up your red matter bomb, and then use this to beam yourself anywhere in the quadrant.
Spock: Thank you, Mr. Scott. Provided that Romulan miner doesn't show up to distract me, I shall be beaming back here when I'm done.
Scotty: Mr. Spock, don't you think we should share this breakthrough with Starfleet. Instantaneous beaming anywhere in the galaxy could have its advantages.
Spock: Mr. Scott, how much interaction have you had with Starfleet of this era?
Scotty: Just that time I was on the Enterprise with the Frenchman commanding, with the android and Klingon officers.
Spock: Let me tell you, you give something like transwarp beaming to contemporary Starfleet they'll complain about it robbing them of the human condition and toss it in a vault along with all the other technological breakthroughs of the past fifty years.
