The Boingo aggregated hotspot network encompasses whole city: It's the beginning of things to come, in which entire metropolitan-scale networks are added to the roaming networks of hotspot aggregators, or are part of peering arrangements among like partners, city to city. Taipei's Wifly network, which spans most of the town with Wi-Fi, will be available through a single account using Boingo's software. This isn't free roaming; most of Boingo's roaming outside of the U.S. involves prenegotiated, discounted fees. All Boingo's locations in Taipei, for instance, are currently tagged as Premium Locations with per-minute charges.
