Am trying to think in 3D.
The only way there is NOT a route to a volume in space (let's call this "Federation Territory") from another volume (say it's the Romulan's) is if the second voluma is completely enclosed by a lage volume (defined as "the neutral zone")
Also, Spock made a presentation in "Balance of Terror" (but not in 3D) when in TOS was established a "Klingon Neutral Zone"? The first time I ever heard that was in The Wrath of Khan, and in that movie it was a ovoid shape:
And not ver big, for it seems the Enterprise can get ti its center in less than a minute. Seemingly not enough to contain an empire.
