Free WiFi on buses

Tur Bus and Claro Chile started a free service last week that lets passengers traveling with them between Santiago and different destination in the 5th region (most typically Viña del Mar and Valparaíso) to have access to WiFi (3G network). Only problem is that only 10 users can be connected at any one time but at least it is better than none.

To begin with 90 buses on the Santiago – Casa Blanca – Valparaíso route will have this free service in place and they look to extend it to other parts over the year.

Apparently the same service has already been running for around a year on the two-floor buses of the “Talca, Paris y Londres” bus company based in Talca.

Does anyone else know of any buses with this service either in Chile or other parts of South America?
Has anyone used the Wifi on any of the buses on the Valparaíso route?
