There's also Hurricane Electric's free IPv6 tunnels.

BTW: one issue that I have seen with IPv6 and address privacy extensions
is that, since temporary address handling moved to user-space
(NetworkManager I guess?) instead of kernel-space, temporary addresses
are expired even when they are still in use.  This affects anything that
uses long-lived sessions (such as SSH to a server) and is highly
annoying.

The RFC (4941 section 3.4) says:

  "As an optional optimization, an implementation MAY remove a
   deprecated temporary address that is not in use by applications or
   upper layers as detailed in Section 6."
