I got to thinking about this for a while, is it possible to host a website over a 3g connection? not from a mobile device but from a full server, if you were to have it in a car, could you host the site from there?
The only way I thought it possible was if port 80 traffic was forwarded to the ip address of the server from the 3g provider, and then obviously point the DNS address of the website to the specific tower?
