I can tell you that when I went to MIT, I found lectures in many courses superfluous. Entertaining, but I was easily able to coast through some classes just by dropping in at the end of a lecture to drop off last week's homework and pick up the current week's. I was able to get the meat of the course entirely from the printed material.
Mind you, there were also many courses for which this wasn't true. For instance, Theory of Algebra and one on computational automata (eg. Turing machines) had only the lecture as source material, with very sketchy course notes, so for those it was imperative to show up.
MIT's lectures are always good, but there are those of us who, given adequate printed material, can function and excel without them.

I recall going to MIT in the early 80's and paying $5-7k per semester (just tuition). I'm surprised to see it hasn't gotten too much higher, about $15k now. Here's a link to the prices, which I found a bit hard to find on their website:
Alas, I didn't graduate (ran out of money at the time) and don't see a way to get back into it. They don't seem to have any pages targeted at people who want to resume a long-interrupted stay.
I, too, use plussed addresses (available to anyone who uses sendmail as their MTA). Alas, a great many overzealous webmasters code overly-aggressive validation in online forms that excludes use of the plus.
Egress filtering is only good for the IP's "owned" by a router, so you just need to spoof within that potentially large space.
I can imagine setting up a "spoof-ability" analysis server: Send it a spoofed packet with your real IP as the data, and after up to 31 attempts (using more and more bits of your real source address) you can determine how "spoofy" you can be, based on which packets generate replies.
The value of open source is not the cost of acquisition of the code, but the openness of the protocols and file formats. This protects you from the vendor lock-in that makes a monopoly product so expensive in the long run.
Don't forget the Instant Replay feature! Countless times I've listened to radio (or watched a movie in a theater) and my attention drifted, or something was garbled, or a noise outside obscured a word, and I wished I could jump back in time 8 seconds to listen to something I missed.
And the 8 second jump-back can be repeated to the limit of the capture buffer (typically 30 minutes or a show boundary for TiVo). So if I were to get into the car 10 minutes into a 30-minute program and decide I wanted to listen from the beginning, I could do so.
The free market is about avoiding violence in human interaction. Whether one is a consumer or producer, a human should have the right not to be coerced into a transaction she doesn't want to participate in, no matter the reason for the avoidance.
And this isn't a zero-sum game. In the absence of violence, trades occur only if both parties perceive a benefit. A net loss occurs only in the presence of coercion, or because an agent makes a bad decision (in which case the loss is self-imposed).
Somebody send this guy to economics school. It's unbelievable how many fallacies were in that post.
Money is a good, just like programming. It just happens to be a convenient good for barter. The fact that different currencies have different values per unit is irrelevant. That's what exchange rates are for. Or can't your programming environment handle fractions?
And it's not about your rights. It's about the consumer's rights. She gets to choose who to buy from, and you have no right to deny her that choice, or to force her to buy from you. To do so is to be no better than a mobster running a protection racket.
Now that you've analyzed the time relationship of the responses, how about doing analysis of the spatial response? Get geographical data on all the IP's that made web requests and display the result as an animated map.
Sort of like those little cigarette-sized keyboard spies.
You'd need two of these back-to-back, with some smarts in the middle. (Does the thing auto-sense polarity or can you get it in a null-cable version?) In a typical environment, it would need a DHCP client to get its own address and a DHCP relay to pass requests for the box it's "hubbing" (really proxying) for.
One might assume that a fat pipe like 100 Mbps fiber would eliminate all contention for your line. Alas, big queues in ISP routers tend to cause problems on your fat pipe when a big download runs in parallel with your interactive traffic. I've found that the WonderShaper is great for both my residential gateway and my colocated game/web/ftp server. It suppresses queuing at the ISP, so that my own gateway can set priority policies on my packets.
It's not stupid if you realize how many customers can't do the math and think 5 GB is a limit they might hit. Those smart enough to know how much 5GB is are probably the same people who will want to run servers.
Not enough to run a bandwidth-hungry game server, but still respectable. Certainly adequate for web, FTP, and email. (Until you're slash-dotted.)
If you want to run a game server, consider a colo. My team uses The NetGamer which shares their 100 Mbps Cogent fiber in 2 Mbps (uncapped) units for a reasonable price.
TeamSpeak is a gamers' communication system similar to RogerWilco or GameVoice. It's notable for having both server and client available for Linux as well as Windows. A Mac port is underway.
One can bind a key to push-to-talk that's still intercepted when one's game has focus.
One feature I find missing is the ability to bind push-to-talk to a mouse button. (It can do this in the Win32 client.) If anyone knows how to do that, please post in the TS forums.

I'm thinking at this point that finishing my degree will end up being part of my retirement plans.
Nah, hit him with the CAT-5 o' nine tails.

Alas, there are some associated risks.
Unless the poster asks for a personal reply, don't cc his personal address. Send the reply to the list, so everyone (including the poster) benefits.
No, beat them with the CAT-5 o' nine tails instead!

How does change notification work in Reiser 4? Is it publish/subcribe (efficient) or polling (as FAM does)? How does it interact with security?

Oh, wait, that's when you correlate multiple DNS databases.

If there's coercion, then you don't have a free market. That violates the basic definition.

As long as you're in the DNS code fixing the ignored TTL's, add some support for SRV records. I'm tired of typing "www".

60*60*24*30 = 2,592,000 seconds in a month
5 GB * 8 (bits/byte) / 2.5Msecs = 16 kbps of 24x7 data.
