IP v6 (to give TCP v6 its more formal name) shouldn't impact home users at all - it's only really being asked for in the US Federal market, and its unlikely to be required for all Internet users for a while.
Why ? IP v4 was going to run out of addresses to give people, until some clever bods came up with the idea of Network Address Translation, which obviates the need for everyone in the world to have their unique address, and instead only the device at the edge of the network, which directly connects to the Internet, needs one, and it mediates between devices inside the network which want to access resources on the Internet. IP v6 allows for enough addresses for everyone to have lots.
If you've got an IPv6 stack installed on your home puter, I doubt your broadband access device would understand it is it used it anyway.
