If they can track a mortar round, then they can keep a laser focused on a launch vehicle.  And if they can build one of these, they can build many, and focus them all on the launcher.  So now if we can get a launch vehicle that can take the heat and turn it into thrust, Keith’s vision of low cost launching becomes reality.
Actually, mortar rounds might be slow and easy targets. Stuff in space moves on the order of km/s, while mortars move at most a few hundred m/s ( http://hypertextbook.com/facts/2003/GabrielaBis.shtml )
Still, good tracking.
