'Mobile Internet Device's' to make a ...

Is it's is possible to use a 'Mobile Internet Device' for a WiFi hub????

I know I can connect my MacMini to the internet with one of these devices but is it viable to then make a WiFi network on the AirPort that my iPhone and Wii could then access the internet over?

It is NOT possible to directly connect to these USB's and join the internet as it is not a WiFi device. But is it possible to connect the MacMini to the internet and then set up a WiFi zone? "If So" what are the pitfalls or problems that anyone have found?!?.

I also can not directly connect to the internet as I do not wish to get locked into a fix line rental contract as I rent my room at the moment.

Any Help would be gratefully appreciated
