Wireless Internet...One Lump or Two?

I saw a link on PocketPCPassion.com (not a typical source of info for macrumors, granted) that seems pretty interesting. Apparently coffee-giant Starbucks and Microsoft are teaming up to deliver wireless internet access in Starbucks locations across the country, using MobilStar Network Corp's wireless broadband network. Interesting stuff. Does anyone know if this is the increasingly common 802.11 (AirPort-friendly) ethernet?

While I don't have an AirPort-enabled notebook of any sort, I must say I'd not mind a little casual browsing on my iPAQ PocketPC (a traitorous move, I know) while sipping a venti White Chocolate Mocha...
