Comment (by gdt):

 A few comments:
  * the URL of your git repo/branch should probably be in this ticket
  * Probably someone (you?) should file a separate ticket for making the
 WUI listen on ::1 (and presumably then the CLI interface could use that
 next, another ticket).
  * whether a node is willing to use v4 vs v6 for outgoing connections
 should be separate from whether the node listens on v4 or v6 (foolscap)
  * the concept of the port file seems a little off.   nodes listen on an
 address/port pair, or rather a set of them.  what port means now is "put
 this together with INADDR_ANY".  But, it could be "put it with INADDR_ANY,
 and also with INADDR6_ANY".   So probably the node config needs a config
 to list the address families on which to listen, defaulting to all OS-
 supported families.  (For extra credit, test on a BSD system without INET
 in the kernel - I need to see if that still builds, and if not fix it.)  I
 suggest "IncomingFamiles = inet6, inet", being a set.
  * for outgoing connections, the introducer furl, or data from the
 introducer, will have a list of addresses.  I think it makes sense to 1)
 include a list of acceptable address families, defaulting to all OS-
 supported families and 2) have a way to express preference.  For
 preference, I would start with v6, following the modern tradition.   So I
 can see this being a "OutgoingFamilies = inet6, inet" and it being a list
 rather than a set.
