McCarran Airport in Las Vegas recently started offering free wi-fi. That's great and all, but they've got it so locked down you can't do much with it. I can't connect to any instant messaging servers and I can't get my e-mail via secure IMAP from work. I was eventually able to get the e-mail by tunneling through our VPN, but still no solution for the instant messaging. I've still got an hour until my flight leaves, and while web access is better than nothing, denying e-mail and IM traffic is absurd. Update: It's also slooow as molasses. I've got pretty good signal strength, but am getting completely erratic connections. They put this in for the CES show that started today, and as far as I'm concerned, it's a failure.
