ost_uid0]My mistake.
I meant subspace.
Ok:
Coaxial drive --> "Vis a Vis"
Quantum slipstream --> "Hope and Fear"
Transwarp drive --> "Threshold"
Subspace corridors --> "Dragons Teeth"
Voyager faster-than-warp propulsion technology you didn't mention:
Caretakers array
Subspace catapult
Q-juniors spacial rift deflector-configuration
Borg transwarp hub
Borg intergalaxial rift deflector-configuration
And subspace corridors really aren't a form of technology, so I'll add:
Wormholes
Q teleportation[/color
