Just pick up an Apple Airport Extreme WiFi base station. They're "mesh"-able so you can stack additional units into a network to expand it out -- but for your use case, you can set up a guest access network that you can change the password to. This way, your base network does not have to change their settings at all, and you can simply set up the guest network on a per event basis with new credentials.

Unit: http://store.apple.com/us/product/MD031/AirPort-Extreme?afid=p219|GOUS&cid=AOS-US-KWG
Cost: $179

Upside, you also get some wicked strong WiFi, dual band 802.11n/a/b/g.
Downside, max out @ 50 clients (according to product page)

What? People competing to be considered funny? What's this world coming to?!

"Bite the wax tadpole" is my favorite bit of gibberish. I use that phrase all the time whenever someone says something that is clearly obfuscated bullshit :-)

Maybe because, according to the poll results so far, there are more people in the 21-25 (18%) and 26-30 (19%) ranges than in the 35+ range (14%)? That sure looks like a long tail to me.

Yes, our mileage sucks, but what exactly is the problem here?

Why do you continue maintaining that 10 MB drive, may I ask?

Digger, please.

Reminds me of Dune. "I hold at your neck the gom jabbar."

I'd prefer that people not use either show as a basis for their understanding of reality. It's not as if CSI and Law & Order are the only available options for learning about criminal justice.

Sometimes I walk up escalators. Sometimes I ride up escalators. I live in Los Angeles. I'm not obese. A given person does not always do the same things the same way every time.

So basically, you're saying that people should get their comprehension of the legal system not from this fictional show that alters reality for dramatic effect, but instead from this other fictional show that alters reality for dramatic effect. That sounds like a great idea.~

Yeah... Microsoft's idea of having a background on something, an idea which they invented, and no one else had ever done before!

This one single study is quite fascinating! I can't wait to see other, corroborating studies. Until then, of course, I'm going to withhold acceptance of any conclusions claimed by the study.

Excellent characterization of the problem.

One must keep in mind though, that not every distributor/production company is part of the Hollywood cartel, or necessarily agrees with their views on copyright.

...and?
