TechCrunch shows a survey screen that asks the subject what they'd think about Yahoo! Messenger On-the-Road: The service would potentially be offered at over 30,000 hotspot worldwide for $7.95 per month flat rate or $2.95 for two hours of Yahoo! Messenger usage. The 30K hotspots and $7.95/month rate matches Boingo's statistics and its offer for VoIP with Skype, so perhaps Boingo would be the platform behind this.
It's an odd trend to see specific services being offered, such as the Nintendo DS Wi-Fi connection (which Nintendo offers at no cost, subsidizing it for its buyers), rather than generic Wi-Fi for all applications. It's about the stupid network, isn't it? But this isn't so much about smartening up a network as striating it for the purposes of providing a better rate for a specific activity, like VoIP.
