Solutions for those locked in IPv4:

Set up a tunnel on a machine: Teredo for a single host, or 6to4/6in4/AYIYA via HE or SixXS, then use that machine as a router to distribute a /64.

For those with an Apple Airport Extreme or a Time Capsule, using the Airport Utility 5.x you can trivially set up a 6to4 tunnel if you have a public IPv4 address on its WAN side, or easily set up a HE 6in4 tunnel.

It takes me from 5min to 15min to enable a machine or a whole network with internet-enabled IPv6.
