Hi, this is a newbie question again but a very valid one. My data plan is 8 GB per month that's max. If I use any of the above mentioned connection methods, they act like server-client basis. Won't that raise charges from my ISP? If I had to pay for moving files between two computers networked locally, then there won't be any juice left for browsing internet and so on. In general how does the ISP keep track of how much I've downloaded? Will my router tell them i've received this much packets this month and so on?
