On Tactical Hyperdrive

While reflecting on Full Thrust, CBF's Raiders, and BattleShift today, I came the realization that the reason tactical hyperdrives, warp-gates, and cloaking devies are interesting to me is that they are some of the few mechanics in starship wargaming that really serve to differentiate it from naval (or for the 3d freaks, aerial) wargames.  The other main ones I can think of / see in practice are momentum-driven movement (doesn't work so well in high-friction fluids) and something like CBF's regenerating / faceted shields (no current technological analog), but those both bear much higher mechanical overhead than warp tech.
