Found this over at onepagerules.com a while ago and the idea sounds very interesting. It's about making both the range (of missile weapons) as well as the movement of units "unlimited" in a skirmish wargame.
The people at onepagerules created a experimental wargame "Covering Fire!" around those rules:

The main advantage is of course to speed up gameplay a lot (no more measuring distances etc.):
Personally, I would modify the rules a bit because "unlimited" sounds way too powerful to me:
1. Players activate their units in alternating order.
2. Each unit can be activated once per turn.
3. When a unit becomes activated it has 1-3 Action Points (AP) to spend
4. The AP can be spend on various actions.
Lets go into detail with some of the possible actions:
4.1 MOVEMENT - A movement action allows the unit to move straightforward as much as the player wants to (unlimited), with a few restrictions in mind:
- When the unit turns (by any amount of degrees), it has to end its move.
- When the unit fully enters or exits a terrain, it has to end its move.
- When a unit is "intercepted" while moving, it has to end its move.
Intercepting happens when the moving unit comes into LOS of another unit that is on "overwatch".
4.2 SHOOTING - A shooting action allows the unit to shoot at another unit, again with a few restrictions in mind:
- Only units with missile weapons can shoot.
- A unit can only shoot at the closest available target.
- The target has to be within LOS of the unit.
- Besides that, shooting range is "unlimited".
4.3 OVERWATCH - for one action point, a unit can go into overwatch. This allows the unit to save up the action point for later. When an opponents unit moves into LOS, the unit can spend its action point in order to counter-charge or counter-fire at the opponents unit. This also forces the opponents unit to stop movement.
Any thoughts on this? Sounds like a lot of freedom to me, but its also risky to play with the fire of "unlimited".
