Not that I've actually tried it yet, but JoikuSpot looks gorgeous - head-slappingly obvious in retrospect (and only in retrospect) like many fantastic ideas and I suspect, genuinely disruptive. Leaving aside the irony that this positions 3G as the bearer of the "wi-fi-everywhere dream" peddled for nearly a decade now... I wonder what this'll lead to, particularly once JoikuSpot or a competing product offers not just HTTP but full internet access, and flat-rate data is more prevalent? What would the mobile equivalent of FON be like? How would it differ to accommodate speed, pricing and availability fluctuations?

Imagine an MVNO which piggybacked not just onto one large operator with whom it has a Big Commercial Agreement in place, but all of them, quietly and unobtrusively...
