Also, and I didn't make this clear, the coherence of the beam is irrelevant to the discussion. Of far more importance is the fact that it is monochromatic. Which allows you to size the lens system for that specific wavelength, instead of trying to average over a spectrum. Which, in turn, allows you to collimate the the beam to very high precision. Ideally, you would get perfectly parallel rays with no dispersion at any distance.
Unfortunately, real lenses couldn't be machined to that precision, and even if they could, diffraction would STILL prevent it from being perfectly columnar. The diffraction limit does depend on wavelength, and is worse for shorter wavelengths, so I suppose it could be part of the reason, but green is pretty close to red in the grand scheme of things.
There is dust in all of the air. Now consider that the beam is actually a cone, with a real diameter, and if you're using it for stargazing, you will be looking at it at a quite oblique angle, since you'll be holding it and pointing away from yourself. So the optical depth of illuminated dusty air in your field of view is actually quite thick. Thick enough apparently, that enough dust bounces light back to you for you to see the beam.
Those powerful green lasers are used in backyard astronomy to point out astronomical objects. There is enough dust in the optical path for the laser to be visible at grazing angles, such as when it is pointing towards or away from you. So all the helicopter crew would have to do is look at where the beam pointed and go there. At only 500 ft, they'd probably be able to see the person holding it, although not well enough to make a description.
The only problem is, they could've released 5 games in that time period and been making actual money. Further, from the various trailers, it looks like they may have made up to the better part of each of somewhere between one and four additional games without finishing and releasing any of them.
If everybody was flashing bright lights all the time, and some people were flashing lights bright enough to *cause burns*, the yes, you would see regulation of colors. It's a simple traffic problem: you can't have everyone in the intersection at once, so you've got to regulate it somehow. The FCC does this by licensing transmitters, which you should be WELL aware of if, as you say, you're a ham.
You'd also be aware that *any* transmission at the very least increases the noise floor. The bandwidth is inherently limited, even if you take the best precautions available. Not every use of radio is for communications purposes, where you could just bump the transmit power. Radio-astronomy also has a legitimate claim to access to the spectrum, which must be balanced with our desire for communications modes.
So, in the case of 700 mhz, which many groups would like access to transmit on, how do you decide who to give the license (or licenses) to? You can't give them to everybody. How would you propose deciding which services would be of the most benefit to society to license in that band?
And this is easier and cheaper than just ordering a few hundred cards from a local print shop, or online business card printing company? I mean, factoring in ink, paper, depreciation of the printer, amortization of the card-cutting machine, and the time spent getting everything "just right" it doesn't seem possible to do better than ordering.

It'll be about details. Mostly humorous.
There will be strippers you can pay, and rob. There will be pool-tables with semi-realistic billiard ball physics. There will be sinks you can smash and urinals you can piss in (and you'll gain health for this for some reason).
You won't be stuck some place with a 2-inch curb you can't climb over to keep you in. Instead, the map boundaries will seem reasonable. Or at least, physical. You might still question why someone built a building across a four-lane street...
And there will be genre-jokes. Perhaps there will even be an arcade with a working version of Ms. Astro Chicken or something, to which Duke makes some comment about it taking so long to come out and not being worth the wait.
That's the first problem. Printers routinely report that they are low on ink even when they aren't, and in some cases there are still hundreds of pages worth of ink left.
Although I find it despicable that printers might under-report their ink capacity (though I always though it was a "buy ink" warning rather than a "put new ink in" warning. An important distinction, as you want to have fresh ink handy *before* you actually run out), I find it very difficult to believe that even the most unethical manufacture would under-report when hundreds of pages remain on a product that is only designed to handle circa 200 pages to begin with.
Now I have noticed, on a family member's HP, that it is printing color even when a page is pure black text. This seems particularly wasteful to me, and when I looked at it, I couldn't figure out if it was a setting, or just fantastically poor design decisions.
It was only a problem for crappy manufacturers like HP who include the ink with the cartridge. Guys like Canon, who not only had separate inks, but separately removable heads and periodically cleaned the heads automatically if you didn't print anything, as long as you left them plugged in and had a superior paper path that avoided bending never got any press. Apparently, they didn't sell enough of their far superior printers, so they switched to PIXMA to get in on the same scam as HP.
How often do you really need good color performance, though. For presentations, color lasers rock. For photos, dye sub is a good choice.
Depending on how frequent you need photos, CVS and the various online print houses can be your friend. Last time I did the math, it was cheaper to get 8"x10" photo printed at CVS than from my own "photorealistic" inkjet printer. And quite a bit faster (including transit times) if I had more than one to print.
Heck, for a home user, I'd say get a B&W laser (it's handy to have something that prints lying around, and toner doesn't dry out in the nozzles if you don't use it), and get those rare color presentations printed at Kinkos. Never buy more equipment than you're going to regularly use. Let someone else sink the capital costs.
A) keep a giant spool of patch cable around, of which they'll use maybe 10%
and
B) crimp all their assorted lengths of wire themselves? There're ten conductors in cat-5. And you have to line them up at both ends. That's tricky. The only time I attempted it, I ended up with a noisy cable that wouldn't do more than 10mpbs.
On the other hand, the "unmetered download area" is a kind of support that they generously do out of the goodness of their hearts. Or for some other reason, the point is that by having OO.org downloads there, they're expending resources to make it easier for their customers to download it.
Enter the competing product. Does it really make sense to put effort into making your competitors products easier to get? If they didn't already have OO.org in the d/l area, They certainly wouldn't be well advised to add it, so what's the big deal about them discontinuing their support of a competing product? It's not like they've banned downloads directly from OO.org themselves.
There is so much overmodulation and distortion in concert venues that one could argue that seeing the band play live is not like listening to the CD. Unless you're listening to an acoustic band in a small setting. You can't get much "more real" than that.
That's when they're done poorly. Homeworld handled the whole "limited resources" level rather well, for the most part, by putting them all at the beginning. The only problem was that if you made large mistakes in early levels or chose your fleet composition poorly, you could make the final level impossible to win.
He might be a little old to play Bilbo as he was well cast to play a Bilbo who settled down for quite some time, but much older than Bilbo was when Hobbit happened.
But who, as a result of the ring's influence, hadn't appeared to have aged a day in something like 50 years. Bilbo was already somewhat advanced (at least late middle-ages) in years when the events of "the hobbit" took place.
They had to take out Bombadil, they also took out the half of the work which even made Bombadil relevant: The whole relationship between language, song, and the nature of the universe theme was axed.
Perhaps because the songs Tolkien penned probably wouldn't have translated well to actually being sung, and including them would've made the film into some kind of weird musical which wouldn't have featured nearly enough gratuitous shots of Liv Tyler.
I've actually wondered if there are other factors going into those numbers. Is infant mortality being taken into account? If so, how? For instance, A premie that doesn't make it will put a big hit on "average life expectancy" unless the miscarriage that would've been the result with inferior medicine is also factored in.
What is the abortion rate in those countries? Amnio-test abortions would improve the "average life expectancy" for cultures that have no stigma against it, cultures that most certainly wouldn't count abortions as "early deaths" for statistical reasons.
It would certainly not be too difficult to manipulate the statistics to support whatever claim you want to make, especially if the real life-expectancies are actually quite close.
Further, It's probably not medicine that is responsible for the jumps in life expectancy experienced by all of the countries mentioned, but modern farming, and it's resultant near-universal availability of nutritious foods.

So, I assume the money's pretty good, then? 'cause otherwise I can't imagine a reason to even get involved in a business like that.
