Here in the UK I discovered that in addition to T-Mobile, BT Openzone and The Cloud, Surf and Sip seems to have a good presence thanks to it being the Wi-Fi provider for Caffe Nero.
And since Devicescape already supported the Surf and Sip hotspots in San Francisco, both natively and through Boingo roaming, I was able to login automatically as soon as I walked through the door.
John is Devicescape's CTO.
