Comment (by lathiat):

 I was talking on IRC with marcopg and I just thought i'd chime in with a
 few usefull bits of information

  - Rather than parsing /proc, you could use SIOCGIFCONF (Example:
 http://www-128.ibm.com/developerworks/aix/library/au-ioctl-socket.html)
  - You could also use netlink, I find this far nicer in Avahi not sure how
 easy it is to "one-shot" though.
  - When using Avahi with IPv6, or IPv6 in general watch out for link-local
 addresses, they are special in that when using them you *must* bind to a
 specific interface in order to make use of them (as all interfaces have
 link local addresses, which one to send it out would otherwise be
 ambiguous) -- Avahi can provide the client applications which this
 information. -- Note that IPv4LL IPs do not have this as a *hard*
 requirement but if you had more than 1 interface up it could be usefull.
