867	use ipv6	warner	warner	"Shawn Willden points out that IPv6 is a likely way to deal with the servers-behind-NAT problem (#169, #445, #49, #50), since a lot of ISPs offer v6 tunnel services these days, which effectively gives the server host a publically-reachable v6 address.

To make this work, we need a couple of things, probably in the following order:

 * python must handle v6 addresses, in the {{{socket}}} module
 * twisted must handle v6 addresses: connecting to them, reporting them when asking a socket who it is connected to, and enumerating them on listenable interfaces. The existing {{{IPv4Address}}} class must grow a corresponding {{{IPv6Address}}} partner.
 * foolscap must handle them: putting them in connection hints ([http://foolscap.lothar.com/trac/ticket/60 foolscap#60] has some notes on formats), connecting to them, etc
 * tahoe must handle them: formatting them into Welcome page listings, passing them through the Introducer without problems, logging them correctly

Let's collect pointers to other tickets (especially the twisted ones) and progress reports here.
