By using Unique Local Addresses (ULA's) http://www.ietf.org/internet-drafts/ draft-ietf-ipv6-unique-local-addr-09.txt Which is almost a RFC btw(*).

They are not the only way and really you don't want them. Example: Your girlfriend is living on the other side of the road, she has a hunderd IP devices (computers, ipod, fridge.. you name it). You have also the same type of setup and because you love her so much you want to give her fast access to your cool warez server which you have got running on one of your leet quad xeon debian boxes. Now if both of you are using fec0::/64. Who of the two is going to take the burden of renumbering (adjusting configs: firewalls, dns.... lot of textfiles.. etc)... You or her? That is where ULA comes in, because they are unique you can simply use them, set a route to your girlfriends router and on hers one to you, done. Scale the above up too two networks with 10.000 devices each, have fun renumbering then.... *that* is why they deprecated the site-local stuff. Just like RFC1918 it looks good but gives a huge headache afterward.
