Very interesting! I suppose it's a possibility for there to be these types of internet providers here in the States... just none of them are in my area. To get back w/ the OP question, and w/ bab providing the math for usage, it would take quite a bit of Facetime to soak up even the 10GB of Broadband internet iHolo mentioned. However, if the OP was using Facetime over their 3G via a Jailbreak tweak... it wouldn't take too awful long to hit the 200MB (smallest data package w/ At&t) to 2GB+ that most Stateside wireless carriers offer in data.
