The latest beta version of Skype (for OSX only, apparently) offers something called “Skype Access”, which makes it possible to pay for access to commercial WiFi networks through a per minute basis using your SkypeOut account.
I recall reading this when I downloaded the latest beta a couple of weeks ago, but didn’t think much about it before I opened my MacBook at the Brussels airport last week and saw a “do you want to pay using SkypeOut” message on screen. I often check to see if there are any available networks around airports, but most of the time you have to pay some ridiculous amount of money for connecting in a few hours (in Europe that is, in the US I have come across many airports that provide WiFi for free). However, most of the time I only need to access the internet for a few minutes to send and receive e-mails and check a few things online. Well, now I was connected to the WiFi in Brussels airport for 1 minute and 50 seconds, and paid only NOK 1,25 per minute. Great!
