Hey, tdvance, my thoughts exactly. If man can do it, man will do it. And if man can make money with it, man will do it on the double.
Personally, my fave idea (as it is, to my best knowledge, originally mine) is to shoot a buckshot load, say a few tons, of metallic pebbles into an orbit that counterrotates with that of Earth (means you have to reach 58 km/s, which poses a slight problem). Then, half a year later, on the other side of the Sun, the buckshot will enter Earth's atmopshere at maximum velocity, creating a predictable shower of brilliant fireballs. If you choose the right metals and create multilayered balls, you get multicolor effects like in fireworks when they burn up in the atmosphere.
