I'm really hoping to avoid USB if at all possible. The wholly integrated HSPA+/LTE modems that have a 100BaseTX ethernet interface are quite expensive, like the basic Opengear model that is $380.
USB could work with a raspberry pi2 if absolutely necessary. One of the things I can predict, the SIM card + Ting concept will almost certainly not get a public ipv4 address, it'll be behind some some of cgnat with no ports forwarded, so the raspberry pi2 needs to initiate and maintain a persistent SSH connection or similar tunnel (such as a tcp based openvpn tunnel with unique-per-device static point-to-point keys shared by server and client, in which the pi2 is the client).
