  No offense to T-Mobile (or anyone else), but managing 1000's of
hotspots is hard.  When you add large companies who want to use that
network, it becomes nearly impossible.

  We have had a poor response rate from companies wanting to roll out a
global WiFi network.  "Authentication?  What's that?  Why can't we just
have every  WiFi network operator white-list our devices/users/traffic?"

  Really.  So all this talk about PKI && certs is "pie in the sky".  We
can't even convince major players to use *passwords*.

  And their network providers are getting squeezed.  No matter what
T-Mobile does, their revenue from these locations is pretty low, and the
user and corporate demands are high.
