Oh no, now the big bad government is going to censor street maps and make roads "state secrets". Gee, didn't the Soviet Union do that? Look what happened to them.

In my universe, email from ckam...@pobox.com would get rejected by mailservers unless it came from a server in pobox.com.
SPF doesn't cure the problem of spammers setting up superspammers.com, and setting valid SPF signatures, but it could cure the scenario you describe above.
Just using the Atlas as a lifter isn't going to replace the Shuttle. </quote>
You have a point. Which is why I was more than a little upset at the cancellation of the X38 project. A few more years (today, had it gone to orbit last year like it was supposed to), and we might have seen the creation of a full-size flight article. Granted, the MPLM capabilities in the airframe might not have been there, but crew exchange surely would have mated to an Atlas V booster. Even as a cargo vessel, the X38 demonstrator might have worked. Sure total cargo load is lower, 400-600kg, maybe. And reusability is a concern. But autonomous retrieval isn't.
Even the Atlas V doesn't eliminate one of the biggest concerns I've always had with the Shuttle, which are those damn solids. At least with a small craft like the X38 (with an appropriate rocket booster), you could decouple the craft from the booster stack in the event of a catastrophe. I have to grant it to Thiokol, though, those are some damn reliable SRBs.
Atlas and the X38 present our best opportunity (IMNSHO), today, of retiring the shuttle in the next decade. We wouldn't even need the shuttle to validate it. Any rocket in the Atlas family could launch the X38 demonstrator. The full scale article is only 12,000kg. Not counting structural integrity of the airframe, that leaves a lot of mass on an Atlas V for cargo.
Spacelab is the remaining STS cargo that would suffer if it was grounded. With a 5m payload fairing, even Hubble could be serviced via Atlas (two flights, however).
OpenVPN server on a new host on port 80. Linux and Windows clients. Make them a semi-trusted part of your network in order to allow them to send email as you.
In some respects, no email that has your company name on it should come from a server that is not owned by you. But that's a policy decision you must make. I'd hate to have a users laptop start broadcasting Sobig from his broadband connection with MY domain name on it when by using a VPN of some sort, my outgoing virus checkers would catch it.
Granted, not even SPF prevents this problem, but the affirmation that the email WASN'T from your servers can at least prevent other SPF enabled emailers from letting it propagate through the recipients network.
The cure for web-email script timeouts is delayed delivery. I used to have this problem with an Intranet app that I built once upon a time that needed guaranteed delivery of emails entered to customers. While the emails always made it into the database, they often failed when the mailserver was dead or overloaded.
So we built an SMTP client that would do delayed delivery and would be nearly guaranteed to be running on the localhost. Somewhat similar to running procmail on a/dir/mbox and just dropping the emails there. Eventually, the intelligence in procmail/sendmail/postfix will deal with the situation.
Directly sending emails from web apps is bad design, IMNSHO.
Please. Some of the Atlas V configurations are more than capable of lifting the remaining space station components. With the habitat module cancelled (arguably the heaviest of the remaining U.S. modules), Atlas V 551 (~20,000kg) (not yet available, IIRC) could lift almost twice as much as the Shuttle.
Every promising space system was killed, just as it was getting down to the demonstration phase. DC-X, X33, hell, the X38 lifeboat got killed too, and it was passing tests left and right.
Hell, with the X38 we could save a Soyuz rocket a year, and leave astronuts on the space station for longer than 6 months.
No, rocket science is designing the Shuttle Main Engine High Pressure Turbopumps. Making them work for 800 seconds a pop without destroying themselves is just good engineering practices and quality control.
Usually because they're bubbling morons and too interested in preening than paying attention to the world around them. The rest are psychos, glorious in bed, and frightful when angered.
What I don't get is that the IRS will gladly take $100's of thousands in taxes on your income profits, but you can only claim $3000 in losses per year...
Hell, I had that bad a loss with one stock I purchased, and I'm a conservative investor...
All conspiracy theories aside I'm witholding judgement. I've seen convincing arguments, but without firsthand analysis of certain pieces of evidence I pause to give more ammunition to the conspiracy nuts.
Even in 1996, however, had it been a terrorist missile you would have to believe that the government would have stopped at nothing to find them, destroy them and expose that fact, if only to remove blame from the ongoing Naval exercises in the area.
If it was a missile, it could only conceivably have been Navy, simply based on all the damage control they did, and didn't do.

No, just earthquakes and wildfires. ;-)
5 billion dollars a year would fund venturestar. It would fund 5 prototype DC-X vehicles. We'd have our SSTO by now if we'd kill the Shuttle program.

Sorry. I forgot my tag.
Some of us used to. The whole problem with the rave scene in my area is that it's almost always dominated by jail-bait. :-/ It sucks growing old...
Last LAN party I threw drew about 45 amps. I think I'm financing some exec's college tuition at N*Star.

It's interesting to note that the first few parts of the ISS put themselves together.
The Germans had submarine launched ballistic missiles? No shit!?
Or grow a spine.
It's called polyethylene, and it's fairly common stuff.

When a 380 pound guy who looks like a serial killer tells you "Buzz off, I'm shopping, and you're bothering me", they listen.
All in the name of providing low prices by preventing credit card fraud. I'm willing to live with that.
