> especially on the planetary plane We do in fact already concentrate our efforts to look for objects near the ecliptic. It's the number one recommendation followed by amateur asteroid/comet discoverers. But actually, interstellar objects might be more uniformly distributed - even Oort cloud objects are supposedly non-aligned with the ecliptic. If anything, I'd expect interstellar objects to be slightly more likely to come from directions roughly along the galactic plane.
