But I do worry that some day the cloud fairy will turn into the wicked cloud fairy of the west and start charging me for every post, or that the cloud will burst and my data will become inaccessible, which is why I keep a copy of everything I post on my own server (and then I back that up).
Vistar uses even cheaper technology--leased space on a geosynchronous satellite that is in view of all of North America--but its devices can't transmit as much data per burst.
