Remember for each person getting shot in an on-line game, there is someone willingly doing the shooting.
One additional purpose of this could be to desensitize the players to inflicting harm on others, or finding people who never minded much in the first place. For those that do especially well, there is always prison guard duty...
The issue is not funneling money to corporate cronies: embezzling government funds is everybody's national passtime. What is damaging here is the side effect of distorting international markets, pushing otherwise competitive producers out of the market. (though yes, in the short-term consumers love the cheap prices caused by dumping)
A more reasonable comparison would be the support of US farmers with price supports and government loans to exporters, and how this undercuts farmers in the third world.
Designing a decent waveform framing and authentication system is a serious, multi-year commitment, both for the theory and hardware, and there is no reason you should have to do it. What you want to find is an analogous requirement and use what exists.
Sirius and XM Satellite radio are probably not the best place to start, since they use proprietary waveforms, and they are designed to avoid dropouts as you drive around in your car. They do this by combining two satellite signals and hundreds of local terrestrial transponders. While this does lead to few dropouts, it has a latency larger than 5 seconds (no big deal in broadcast radio, but is it for you?).
If you do want to broadcast a protected stream, look at the ITU Digital Video Broadcasting (DVB) standard (see www.dvb.org). While it is aimed as video, it allows for essentially any serial traffic to be concatinated onto a single broadcast and can be protected (stream by stream)at least as well as a DirectTV signal. I wont't say it is "safe", since I don't want to start a flamewar with all those HBO stealers out there. It has specific extentions for audio and for IP, which is how most satellite internet services work (they use many different standards for the return link, but I won't get into that here).
This standard includes a choice of waveforms (mostly QPSK or BPSK), but does not give you a licenced band in which to transmit. I am going to assume that you want to use the unlicenced band, since beginners don't own licenses (no offense).
straight DVB is very narrowband, and would not handle the interference you might expect in that band. you might have to include occasional channel hopping within the unlicenced band to avoid jammers. Read up on this in the Frequency hopping option inside the 802.11 standard. If you are lucky, you will find that someone has implemented what you need in hardware already within that standard.
All of this assumes you are streaming data, since you talked about satellite radio. If you want something more interactive, well , that is a whole 'nuther post.

Finally something I can contribute to slashdot!(says the optical engineer working late):
The collection of mirrors used here is actually a piecewise-flat approximation to a large magnifying mirror, and does magnify the sun, within a margin of error. Augustin Fresnel invented this concept in 1822 for use in lighthouses.
http://www.lanternroom.com/misc/freslens.htm
If you look at the array of mirrors used here, the outer ones curve increasingly inward, just as as if it were a sigle curved mirror that had been cut up and rearranged to fit on a flat board. Any small part of a large curved lense is approximately flat anyway. It is not generally called "magnification" because that is used to talk about enlarging images, and this type of lense, being approximate and cheap, yields pretty blurry images. Still, works great for spotlights and solar concentrators.
Here is another example:

Let us call a spade a spade: the bookstores don't group them as related genres, they group them as books read by uber-nerds.
For example, I bet they were sick and tired of know-it-alls like me disputing how they classified each Orson Scott Card novel.
On the other hand, If they grouped Sci-fi with Romance novels, I might get a date once in a while....
So much has been said about the "slashdot effect" taking down sites. Has anyone looked at using bit-torrent to distribute referenced websites or images that are referenced on slashdot.org?
Not only would it help our community and stop punnishing publishers of interesting stories, it would be a great expample of an important legal use of the technology.
Yes, it will be "close" spatially (briefly), but way off in Velocity. We would be better off pulling in an asteroid from the asteroid belt: Far away in space but not so much "delta V" to overcome.
Besides, don't comets melt this close to the sun? The whole project sounds like bringing a snowball home in your pocket...
You would disguise it as a beat-up accordion file like accountants use. Nobody would give a damn about that.
If all else fails, how about a suitcase that looks like a homeless person's shoppoing cart?
