Inspired by the fuss over in XI+ ("OMG Khan beamed to Kronos retire teh starships Trek is ruined forevah!!!!1!"), here is a list of magical transporter abilities. Feel free to add ones I've forgotten and attack/defend the plausability/implausibility of them.
Transwarp Beaming
From a relatively stationary start to a ship at warp. From Earth all the way to Kronos. A software patch to the regular transporter, invented by Scotty, whose alternate self almost died using it to beam to the Enterprise, and who had previously killed Admiral Archer's beagle when attempting to demonstrate it (Star Trek, Into Darkness)
Subspace Beaming
Across several light-years. A minor modification considered dangerous, known to the Federation and Ferengi. Possibly the same as transwarp beaming. (TNG: "Bloodlines") The Dominion also had transporters with extreme range, they could use theirs to pluck people from distant targets, something Transwarp beaming may be unable to do.
Beaming Into an Alternate Reality
First done accidently during an ion storm, replicated a century later using a handheld gizmo which interfaces with a regular transporter (downloading extra software?) (TOS: "Mirror, Mirror", DS9: "Shattered Mirror" etc.)
Beaming Through Time
With the aid of some time-limited technobabbly particles, O'Brien was able to beam people to various periods in Earth's history. (DS9: "Past Tense")
Cure All/Anti Ageing/Re-Ageing
Where to start? Kirk and Spock are de-aged in TAS: "The Lorelai Signal", the entire crew are made their proper sizes again in "The Terratin Incident", the baby crew are re-aged at the end of "The Counter-clock Incident", Dr. Pulaski is cured of an ageing disease in TNG: "Unnatural Selection", the crew are de-aged into children in "Rascals" and it's reversed the same way at the end. I'm sure there are a few I've forgotten.
Epic Pause Mode
Scotty kept himself alive in the transporter for 70 years, in TNG: "Relics". The guy he was in there with didn't make it.
Splitting, Duplicating and Merging
Kirk is split into good and evil halves in TOS: "The Enemy Within" but both are merged again at the end, Captain Christopher is (pointlessly?) beamed into his slightly-earlier self in "Tomorrow is Yesterday", Will Riker is xeroxed in TNG: "Second Chances", Tuvok and Neelix, with the aid of a magical plant, merged into one being and then somehow separated again months(?) later (VOY: "Tuvix")
So basically, someone with a transporter and the right set of software hacks could beam anywhere in the galaxy, become virtually immortal, skip centuries, raise an army of clones and hop between universes, Sliders-style. Just great.
